Self-Clinching Floating Locking Nuts provide a self-clinching fastener with a floating nut that compensates for mating misalignments to 0.030 inches (0.8 mm) and provides prevailing torque for the mating screw equivalent to MIL-N-250-27 specifications. All self-clinching fasteners install into a round hole, which may be punched or drilled in ductile materials. They provide a permanently attached fastener, which becomes an integral part of the panel or frame and eliminates the problems associated with loose hardware. Self-Clinching fasteners provide added value by speeding initial assembly as well as servicing in the field, keeping costs to a minimum.

Features and Benefits |

Self-clinching fasteners are pressed into holes in sheet metal by applying a steady squeezing force. This results in the cold flow of sheet material, which is displaced by the knurl, into the undercut area on the shank of the fastener. Once fully embedded, the knurled area prevents torque-out during tightening of the mating part. Thread: Self-Locking Internal - ANSI B1.1, 3B / ANSI / ASME B1.13M; (6H ISO metric) Float: 0.015 in. (0.4mm) minimum in all directions from center, 0.030 in. (0.8mm) total Use In: Materials with Rockwell Hardness of B-70 or less |
