Since 1974, Captive Fastener Corporation has been solely dedicated to manufacturing the finest quality self-clinching fasteners for a variety of industrial and electronics equipment produced by major OEMs.
Series CPN & CPR
CPN & CPR Spring-Loaded Plunger Assemblies are used as positioning pins and locking stops on drawer slides and equipment consoles.
CPR series has a hold open feature activated by pulling out the plunger head and rotating it, which allows smooth slide operation.

Series | PEM Cross Reference | Material | Finish | Feature |
CPN | PSL2 | Carbon Steel | Bright Nickel over Copper Flash ASTM B689 | Spring Return |
CPR | PTL2 | Hold Open |

Use in: Cold-rolled Steel or 5052-H34 Aluminum with Rockwell hardness of HRB-80 or less.
Reel Mounted Spacers and Nuts:
Series CRM
CRM Reel Mount nuts and spacers provide a low-installed-cost solution for surface mount hardware. The fasteners are fed from the recyclable reel using “pick and place” equipment and oriented prior to the reflow soldering operation.
Series | PEM Cross Reference | Material | Finish |
CRM | SMTSO | Carbon Steel | Eeltro Tin Plated, ASTM B545, Class A w/ Preservative Coating |

Thread: Internal 2B, ANSI B1.1 (6H, ANSI/ASME B1.13M)
Series CRT, CRTS, CRTA
CRT series fasteners provide a low-installed-cost solution where a clinching fastener with repeat locking torque is required. The design allows for greater reusability and minimizes the possibility of thread damage of the mating screw.
Series | PEM Cross Reference | Material | Finish |
CRT | LK | Carbon Steel | Black Dry Film Lubricant over Zinc Phosphate |
CRTS | LKS | 300 Series Stainless Steel | Black Dry Film Lubricant |
CRTA | LKA | 7075-T6 Aluminum | None |

Thread: Internal 3B, ANSI B1.1 (6H ANSI/ASME B1.13M)
Thread locking performance for CRT & CRTS is equivalent to applicable NASM 25027 specifications.
