PATCH LOCK SET SCREWS

Used when vibration is a problem, patch-lock set screws provide prevailing torque on the screw to prevent back-off.  With a fused nylon patch on the outside diameter, our patch-lock set screws lock in any position -- no need to seat.  They are also reusable several times over.
 
Our patch lock set screws conform to MIL-F-18240, Conf B and are made in the USA to current industry standards.  They are made from alloy steel with hex sockets, cup points and black oxide finish (Rc48-52).  Patch lock set screws can be supplied with brass or nylon tip in alloy or stainless.  Lengths not listed may be available on special order.
