Flat Head Socket Cap Screw Thread Locking Patch Screw Socket

Flat head socket cap screw is also known as countersunk head hexagon socket screw. The screw is commonly used in machine parts, die fixturing, and clamping. The socket head enables driving where there is not sufficient space for wrenches or sockets. The hex socket screw drive has a hexagonal recess and may be driven by a hex wrench, also known as an Allen wrench, Allen key, hex key or inbus as well as by a hex screwdriver (also known as a hex driver) or bit. Tamper-resistant versions with a pin in the recess are available. 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. 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, the 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.
