A free four-page product bulletin profiles Pemhex self-locking, self-clinching fasteners, which feature a nylon hexagonal element that provides a reusable, non-metallic prevailing torque thread lock and prevents galling. These fasteners can be installed permanently in metal sheets as thin as .060"/1.5 mm. Their locking performance meets applicable NASM25027 standards.
The updated Bulletin PL covers specifications, installation procedure, and performance data for these steel (Type PL) and stainless steel (Type PLC) self-locking self-clinching fasteners, which are available in unified and metric thread sizes #4-40 through #10-32 and M3 through M5. A trademarked blue nylon locking element identifies unified fasteners (black for metric fasteners).
These fasteners can be installed in a punched or drilled hole in a sheet by pressing them into place. The fastener's strong knurled collar receives installation force and resists torque.
