Quick-release shaft collar secures components on shafts
It can be difficult for technicians to keep tools and reels secured on smooth shafts. That’s the major reason designers at Amacoil, Aston. Pa., designed EasyLock shaft collars. They hold items on shafts and install quickly without special tools on smooth, case-hardened (Rockwell 55 or higher) ...
Self-Clinching Standoffs for Ultrathin Stainless Steel
Type TSO4 self-clinching stainless-steel standoffs are designed for stacking or spacing components to or from ultrathin stainless-steel panels. The specially hardened fasteners permanently install into stainless-steel sheets as thin as 0.025 in./0.63 mm with only a single mating screw required...
HuckGuard is a zinc-rich basecoat with an organic topcoat that pretreats fasteners from corrosion. The coating lets the company’s HuckBolts and collars sustain up to 1,000 hr of salt-spray testing — with no painting — while those only coated with zinc handle only 100 hr. While Huck...
