Stainless Self Locking Serrated B18 2 2 Threads Hardware Review

Flanged base eliminates the need for a washer when fastening components. Self-locking serrated flange digs into the material being fastened to help prevent loosening. Hex body has six flat sides that a wrench can grip to turn from the side, enabling use when there is no space above the nut. 316 stainless steel provides strength and better corrosion resistance than 18-8 stainless steel, while the plain surface has no finish or coating. Meets ASME B18.2.2 specifications.
