Hillman Fasteners 370345 Conical Plastic Anchor 50 Pack

Product Description

The HILLMAN FASTENERS 370345 is a conical plastic anchor designed for securing fasteners into masonry, concrete, block, or drywall substrates where a reliable threaded grip is required. Each anchor features a tapered, flanged body that expands on screw insertion to lock into the base material. Sized for 14-16 screw threads and measuring 1-3/8 inches in length, these anchors are sold in a 50-pack quantity. They are a standard consumable for electricians, plumbers, HVAC installers, and general contractors who need to anchor conduit, brackets, straps, or equipment to structural surfaces.

These anchors are suited for light- to medium-duty fastening applications in residential and commercial construction. Typical uses include mounting electrical boxes, pipe hangers, duct supports, and equipment brackets to concrete block, brick, or drywall. The flanged head seats flush against the surface and prevents the anchor from being pulled through the hole, providing a clean, stable mount point.

Key Features

• Tapered conical body expands on screw insertion for a secure hold in the base material
• Flanged head prevents pull-through and seats flush against the mounting surface
• Sized for 14-16 screw threads at 1-3/8 inches in length
• Plastic construction resists corrosion in damp or wet installation environments
• 50-pack quantity reduces per-job restocking for production or service work

Compatibility

Designed as an OEM-style replacement and standard-use anchor compatible with 14-16 screw sizes in typical masonry, concrete block, brick, and drywall fastening applications.

Installation Notes

Installation is performed by drilling a correctly sized pilot hole into the substrate, inserting the anchor flush with the surface, and driving the appropriate 14-16 screw to expand the anchor body. Power down any nearby electrical circuits before drilling into walls or structural surfaces. Follow applicable NEC or IPC requirements when anchoring conduit, pipe supports, or equipment. Do not overdrive the screw, as overtightening can crack the plastic anchor body and reduce holding strength.
