ENGINEER PZ-57 Neji-Saurus screw removal pliers

I bought this product for removal of a stripped m2 SSD screw that was properly stuck into my laptop, preventing installation of a m.2 ssd stick for *MONTHS*, blue loctite and all! I previously had purchased a drill bit set, which ended up doing more damage to the screw surface, and not much else. In comparison, these pliers were able to easily and immediately loosened the screw with just a smidge of a twist. I was forced to take it slow and steady, due to the screw being in a location that prevented full rotation. Less than 5 minutes later, it was fully out! The head of the pliers is definitely able to reach into tight spaces, the grip of the jaws onto the head is perfect, and the handles are easy to grab and keep hold of. I recommend this whole-heartedly.

This is a fantastic tool! I own a Hewlet Packard HP ZBook 15 G5 laptop PC which has two slots for M.2 PCIe NVMe SSD cards, and wanted to remove and replace the installed SSD. Despite using the correct size screwdriver for the small M2x3mm cross-head screw holding the board in place, the head of screw quickly stripped. It seems HP, like many other manufacturers, used a strong thread lock compound on the screw, making it almost impossible to remove! I tried using my set of Moody mini screw extractors with no luck. I then tried super-gluing a screwdriver into the head of the screw, but after curing for 24 hours the bond quickly broke when I applied torque to the screwdriver. I purchased these pliers as a last resort, after which I was resolved to sending my laptop to HP to see if they could remove the stripped screw (which would have been an expensive and time-consuming process). The pliers arrived today, and I set to work this evening. The head of the screw is very thin - less than 1mm, by my estimate - however the pliers easily and securely gripped it without sliding off. Because of where the screw is positioned, it is obstructed by part of the inner PC chassis, so I was only able to rotate it perhaps 1 degree at a time. However, after a few minutes easy work I managed to fully unscrew it, and without any damage or scratching to the SSD board and PC chassis. I may never need to use these pliers again, but even for just this one occasion they have saved me considerable time and money, making an incredibly frustrating job quite simple. I should also mention that they're superb quality, over-engineered and finished to a standard I've come to expect from Japanese tools. Best few quid I've spent in quite some time. Highly, highly recommended.

Japanese-made import. Did great on two rounded-off flathead screws when all other methods on the internet failed – rubber band, superglued-in screwdriver tip, using Dremel type tool to cut a groove into the screw face for a flat bladed screwdriver etc (which was unsuccessful as its height was less than 1mm). Squeeze the handles only tightly enough to stop the pliars slipping both around and off the problem screw. And initially it is best to rotate by a few degrees in a controlled manner, as despite the steel construction the contacting ridges on the jaws are necessarily shallow for gripping the outside edges of very small diameter screwheads. Consequently they can be deformed out of shape permanently if too much pressure is applied. A previous reviewer recommended tapping the screw's face if practical to help unstick threads (which I did), applying a light penetrating fluid if rusted or particularly tight is also an idea. Were it allowed, half a star could be knocked off for the seemingly high price of these small pliers, yet it is clearly a specialist tool. 5 stars is definitely justified however when factoring in its high quality Japanese construction, comfortable-to-hold esd-safe handles if you have average sized hands and most of all, the relief of getting out of what are highly frustrating, near impossible situations! I could not find a similar product from another manufacturer. Who knows, maybe thanks to the UK-Japan trade deal signed around 12 months ago these and Engineer's other products will eventually cost less.

Absolutely amazing tool. This is a must have tool!

The tool works exceptionally well for the one reason it was made for. My m.2ssd screw was completely stripped, i tried loads of screw drivers and sizes, rubber band, tape, superglue and normal needle nose pliers. This made quick work of the situation. A bit pricey but if it works it works. Also i am not too sure what the ESD claim here is.

Absolutely amazing tool! Managed to unscrew (with ease) an M2 screw which held the heatsink of HP laptop. Where all other methods failed, and I was about to loose my mind this hero came in and saved the day! Highly recommend!

Worked perfectly for removing a stripped M.2 screw from my SSD card stuck in my old computer motherboard. I tried all the tricks the internet had to offer to remove it but it didnt budge. This was a life saver and made light work of this issue. Definitely a worthwhile tool to have at hand.

Worked for removing a stripped screw on a 2.5" hard disk case, solved my problem. I'd tried other techniques like elastic bands to no effect and was gearing up to try a drop of solder but saw these as another option. Initially I thought it wasn't going to work but but just go slowly. The way these can grip the edge of a screw even when close to the surface makes a world of difference. The smaller size is advantageous for small electronics components. Easy to hold.

Worked as advertised. I was able to remove some stripped screws from the computer motherboard with this.

Tuve una experiencia de terror al ser principiante en estar modificado mi Steam Deck, para amplificar su SSD. Al principio tenía demasiada confianza de que iba a ser un proceso facil, ya que habia tenido poca experiencia haciendo cambios similares. Confiando de mis herramientas (no tan buenas al parecer) barri este tornillo, y hice lo que nunca debes de hacer que es forzarlo hasta que pierda forma. Intente de los dos métodos universales: el del pegamento y la liga de goma. Ninguno funciono. Buscando en foros de Reddit respecto a este tipo de problema, especifico del tornillo del SSD de la Steam Deck, encontre a alguien que sugerio esta herramienta, fue el llamado divino que me hizo tener la solución! Al principio no tenia esperanzas, ya que intente ligeramente hacerlo con otra herramienta similar a esta, pero no funcionó. Pero, la compre aun asi, y vaya que ni fuerza le tuve que poner para sacar el tornillo! Una maravilla de herramienta. Tuve mucho cuidado de no dañar nada de la SSD de fabrica, y no hubo nada de problema. Muy recomendable, al parecer ese tipo de tornillos son un dolor de cabeza, al ser tan delicados. Así que si también sufres de este problema y te llevo a esta herramienta, mi recomendación es: ¡Comprala! Funciona bastante bien

Cada vez son más frecuentes, pero los tornillos M.2 que sujetan las tarjetas de expansión en este formato (normalmente discos SSD y tarjetas de red WiFi) nacieron ya problemáticos: comenzando porque no suelen suministrarse con los SSD y hay que comprarlos aparte en muchas ampliaciones y siguiendo con que su pequeño tamaño son excepcionalmente difíciles de de sacar si pasamos la cabeza del tornillo, añadiendo que suelen estar en sitios muy delicados. Esta herramienta es alicate extractor de tornillos, fabricado por la prestigiosa firma japonesa Engineer. Lo que lo distingue de otros alicates similares son las indentaciones y la forma ovalada de la punta, para maximizar la superficie de contacto con el tornillo. Con ellos se sujeta la cabeza del tornillo por los laterales para poder girarlo. Por supuesto, si el tornillo está completamente a ras, es imposible agarrarlo y la herramienta pierde toda su efectividad aunque sorprende la poquita superficie de contacto que necesita para hacerlo girar. Funciona con el mismo principio que su hermano mayor, el PZ-59 «Neji-Saurus» (enlace) pero para tamaños de tornillo mucho menores. Requiere un poco de paciencia y si el tornillo se muestra demasiado pertinaz o tiene signos de corrosión, es recomendable aplicar un poco de WD-40 y confiar no hacer demasiado estropicio - el WD-40 debe limpiarse con alcohol isopropílico inmediatamente de cualquier placa impresa. Como todas las herramientas de Engineer, está muy bien construida y ofrece una alternativa viable a sacar un tornillo de tamaño muy reducido con la cabeza deformada sin recurrir a métodos potencialmente destructivos como taladrarlo o aplicar la punta de un soldador para deformar la cabeza y acoplar un destornillador directamente. Es una ayuda valiosísima para trabajar con todo tipo de pequeña electrónica, desde portátiles hasta móviles. En mi caso los adquirí para un tornillo deformado en una PS4 Pro y, sin él, seguramente habría tenido que romper parte de la carcasa.

I tried everything to get those stubborn ssd and heat sink screws off my laptop. I tried heat, rubber bands, all the right screwdrivers and the big pliers at home but none worked and everyone told me to get those overpriced vampliers But this mini plier did the job just right It was my last hope and it worked wonderfully

I had my doubts for this and had kept this in wish list for few months, before actually ordering it. One of the screws in the cooling chamber of my laptop was damaged, the screw head was all messed up. The plier is great for M2 screw sizes (laptop screws etc), it is actually not very big in size and that makes it ideal for such screw sizes. Highly recommended, changing thermal paste can give a performance boost and increase the longevity of your laptop, I guess 2.5k is worth the price.
