Socket screws are available in regular cap screw and flat and button type. They are generally alloy or stainless steel, but can be provided in monel or other materials. Socket screws are generally of higher precision since the thread tolerances are more stringent. Many socket screw applications adhere to Mil-Spec requirements which we typically provide from stock. Industries served include military, aerospace, defense, mechanical, original equipment manufacturers, petro-chemical, power generation & mass transit.

National Engineered Fasteners is a certified distributor of Set Screws to the following industries; military, aerospace, defense, mechanical, original equipment manufacturers, petro-chemical, power generation & mass transit. Set Screws are composed of alloy steel, corrosion resisting steel, and Chrome-Nickel. Set Screws are available DFAR compliant.
