Hillman Fasteners 370329 Blue Ribbed Plastic Anchor 100 Pack

Product Description

The HILLMAN FASTENERS 370329 is a blue ribbed plastic anchor designed to provide a secure fastener hold in drywall, plaster, and masonry substrates. Each anchor measures 1-1/4 inches in length and accepts screw sizes 8, 10, and 12, making it a versatile option across a range of light-duty to medium-duty anchoring tasks. The ribbed exterior bites into the pilot hole as the screw is driven, expanding the anchor body to grip the surrounding material. This pack contains 100 anchors, providing sufficient quantity for production work or stocking a service vehicle. Electricians, plumbers, HVAC techs, and general contractors reach for these anchors when securing brackets, straps, and fixtures to hollow or solid wall assemblies.

These anchors are suited for residential and light commercial applications where equipment mounts, pipe hangers, conduit straps, or panel brackets need a reliable attachment point. Common install scenarios include fastening junction box supports, HVAC equipment brackets, and plumbing fixture backing to drywall or plaster walls. The 1/4-inch drill size requirement is standard and pairs with common rotary or hammer drill bits already on most service trucks. The 100-count box format reduces restocking frequency on active job sites.

Installation Notes

Installation is performed with a 1/4-inch drill bit to create a clean pilot hole before seating the anchor flush with the wall surface. Drive the anchor straight and fully seated before inserting the screw to ensure proper expansion and holding strength. Do not overdrive the screw, as excessive torque can strip the anchor body and reduce holding capacity. Follow applicable building codes and the equipment manufacturer fastener requirements when anchoring load-bearing brackets or mechanical system components.
