Value Collection 86853470 Hex Cap Screw 1/2-13 Grade 8 Zinc 10pk

Product Description

The VALUE COLLECTION 86853470 is a fully threaded hex head cap screw designed for heavy-duty mechanical and structural fastening applications. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener delivers high tensile strength and corrosion resistance in demanding service environments. The 1/2-13 UNC thread designation indicates a 1/2-inch nominal diameter with 13 threads per inch, and the shank measures 1-1/2 inches under the head. The zinc coating provides baseline galvanic protection against rust and oxidation. Sold in packs of 10, this screw is a standard choice for mechanical contractors, millwrights, HVAC equipment installers, and general trade professionals who need a reliable, high-strength inch-series fastener.

This fastener is suited for bolted connections in residential and commercial mechanical systems, equipment mounting, structural steel assembly, and general industrial fabrication. The fully threaded shank allows clamping force along the entire fastener length, making it appropriate for thinner material stacks or applications where a nut engages near the bearing surface. Typical uses include equipment base rails, fan deck assemblies, condenser unit mounting, pump brackets, and structural framing connections where Grade 8 strength is specified.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength for critical fastening applications
• Fully threaded shank allows full thread engagement across the entire 1-1/2 inch clamping length
• 1/2-13 UNC thread standard ensures wide compatibility with standard inch-series nuts, washers, and tapped holes
• Zinc-plated finish offers corrosion resistance for indoor and protected outdoor installations
• Sold in a 10-piece pack for job-site convenience and small-quantity procurement

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, flat washers, and lock washers conforming to inch-series fastener standards. Compatible with any tapped or through-hole application specifying a 1/2-13 UNC Grade 8 hex cap screw.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or licensed trade professional following the applicable equipment manufacturer torque specifications for Grade 8 fasteners. Always de-energize and lock out equipment before performing any bolted assembly or disassembly. Use a calibrated torque wrench and appropriate 3/4-inch hex socket or wrench to achieve proper clamp load. Do not mix Grade 8 hardware with lower-grade nuts or tapped holes not rated for the corresponding load.
