AC-0428-2
Floating Self-Clinching Fasteners A4, AS, AC - Unified
Part Aliases: Penn Engineering 169642P009
These fasteners offer both locking and non-locking threads, ideal for providing load-bearing support in thin sheets with up to .030" adjustment for hole misalignment. Featuring a self-clinching design, they ensure quick and easy assembly by simply squeezing them into prepared holes with a standard press, resulting in a flush finish on one side. The floating nut extends fully into the retainer shank, enhancing strength and support in assembly. Made of 300 Series Stainless Steel, they are suitable for use in sheets as thin as .038" with hardness up to HRB 88 on the Rockwell "B" scale. Additionally, a self-locking version is available, meeting NASM25027 specifications. These fasteners not only offer performance but also comply with RoHS regulations.
