PEM PF11™ / PF12™ / PF11M™ / PF12M™ Captive Panel Screws are large knob, spring-loaded screws with a self-clinching mounting style and a knurled or un-knurled (smooth) metal cap. These fasteners incorporate a trademark skirted shoulder on the retainer to provide a positive stop during installation. An optional anti-cross thread feature eases assembly, aligns components, prevents jamming, and slides through clogged internal threads, improving assembly line productivity. PEM PF11 / PF12 / PF11m / PF12M Captive Panel Screws are available in metric or unified threads, with the metric version identified by dimples on the screw head. These panel screws are compliant with Advanced TCA® specifications.
