Simpson Strong-Tie's 3/4 in. GW Gas-Actuated Dome Washer Pin (200 Pack) provides a practical fastening option for attaching compatible materials to concrete and steel without the need for conventional drilled anchors. The integrated washer helps provide a larger bearing surface against the attached material, while gas-actuated installation supports consistent fastening productivity on demanding job sites. Supplied in a 200-count package, these fasteners are useful for contractors performing repetitive fastening tasks involving concrete, steel, and other compatible base materials. Proper tool, load, and substrate compatibility should be verified before installation.
