These fasteners prove handy whenever shop owners and contractors mount vibration prone loads.

- Drive the unit into drilled masonry to trigger the tapered sleeve against the hole walls

- The built in steel nut takes rotational stress while the pin locks the assembly mechanically

- Chromate plating fights humidity so your bolts stay tight indoors without extra maintenance

- Hammer set installation transfers kinetic energy directly into concrete for immediate holding power
