Miniature Metric Screw Blue Nylon Patch Machine Precision Thin Nail

Miniature metric screw is used on electronics, the size is usually between M0.8 to M3.0. Machine screws have a uniform diameter the entire length of the shaft as opposed to tapered screws that have a pointed tip. They are used to fasten machine components, appliances, and more. Ever Hardware provides custom-made fasteners and customizable packaging.

Nylon patch is a pre-applied thread locking coating (typically Nylon), which is fused to internal or external threads of a fastener. The nylon patch is dry to the touch and ready for use right out of the box. Unlike reactive thread lockers, the nylon patch performs immediately upon assembly with no curing time required. When assembled with a mating part, nylon patch is compressed. The engineered plastic (typically a Nylon Patch) resists this compression and acts as a wedge, increasing the metal to metal contact 180° opposite the material. This mechanical force creates a strong, yet fully adjustable lock which will not weaken, even under extreme vibration. Nylon patch screw is commonly known as a prevailing torque type self-locking fastener.

Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent miniature metric screw rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Galvanizing protects in three ways:
It forms a coating of zinc which, when intact, prevents corrosive substances from reaching the underlying steel or iron.
The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
The zinc protects its base metal by corroding before iron. For better results, the application of chromates over zinc is also seen as an industrial trend.
