Fastener SuperStore Now Carries 12-Point Socket Style Allen Nuts!

12-Point Allen Nuts are cylindrical, internally threaded fasteners with a knurled edge. One side of the fastener is threaded to accept a mating screw or bolt, and the opposite end has a 12-point drive that can accept a hex key / allen wrench.

Fastener SuperStore now carries these parts in 24 sizes in alloy steel / black oxide starting at 4-40 and going up to size 1"-14. We also carry eight sizes in 18-8 stainless steel, going from size 4-40 up to size 3/8"-16.

Allen nuts are used when: limited space is available that prohibits external wrenching; where an unassuming, low-profile look is preferred; or where it’s critical to apply precise amounts of torque to complete the fastening. Steel allen nuts provide greater strength than stainless nuts. Stainless nuts offer greater resistance to environmental corrosion.
