PennEngineering® Datasheets for Nuts

Nuts are a type of hardware fastener with a tapped inner diameter. They are used with a mating threaded bolt or rod to secure components. There are many sizes and varieties of nuts; each with a particular fastening purpose. Some nuts can be applied without tools, and others may have special designs to prevent the nut from loosening.

Type CFN broaching fasteners are available for thinner sheet, close-to-edge applications. The locking element provides prevailing torque to eliminate loosening of mating threaded hardware.
Type KF2 and KFS2 - Broaching nuts, internally threaded for mounting on PC boards.
Type S, SS, CLS, and CLSS nuts provide load-bearing threads in thin sheets with high pushout and torque-out resistance. Type SP, PEM 300® nuts provide strong load-bearing threads in stainless...
Type SMPS self-clinching nuts are for installation into ultra-thin sheets. They feature a lower profile and can be mounted closer to the edge of a sheet than other self-clinching nuts.
Type SP, PEM 300® nuts provide strong load-bearing threads in stainless steel sheets as thin as .030”. Type SP is recommended for use in steel or aluminum sheets HRB (Rockwell...
Hex shaped barrel provides larger solder area. Provided on tape and reel. Reduces board handling. Smallest thread size: M1 / #0-80. Minimum sheet thickness 0.5 mm / .020." RoHS compliant.
Meets torque requirements for IFI 100/107 Grade B (unified) and ANSI B18.16.1M (metric) locknuts. Type H is for use in sheet hardness HRB 80 or less on the Rockwell “B”
Screw and spring mount together permanently into the heat sink. Receptacle nut mounts permanently to the PC board. Scew can not be overtightened. Provides even, constant contact of heat sink...
