Value Collection MP39089 Hex Cap Screw 7/16-14 X 3.5 in Grade 8

Product Description

The Value Collection MP39089 is a 7/16-14 x 3.5-inch hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 is the highest common SAE strength grade for inch-series fasteners, making this screw suitable for high-stress structural and mechanical assemblies. The partially threaded shank provides a smooth bearing surface under the head, which is preferred in applications requiring precise clamping force or shear load transfer. This fastener follows UNC thread form and meets ASME B18.2.1 dimensional standards. It is installed by maintenance mechanics, millwrights, and general contractors using standard hex tooling.

This cap screw is used across industrial, mechanical, and structural applications where a high-strength inch-series fastener is required. The 7/16-14 UNC thread size and 3.5-inch length under head make it a common choice for equipment frames, machinery mounts, structural connections, and heavy-duty assemblies. The zinc yellow dichromate finish provides corrosion resistance suitable for indoor and light outdoor environments. Sold in a package quantity of 10 units per order.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank for improved shear resistance and precise clamping
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• UNC (Unified National Coarse) thread form for broad tooling and nut compatibility
• Meets ASME B18.2.1 dimensional standard for hex head cap screws
• Sold in a 10-piece package, minimum order quantity of 1

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 7/16-14 UNC hex nuts, flat washers, and lock washers in structural, industrial, and mechanical assembly applications.

Installation Notes

Install using a standard hex wrench or socket sized for a 7/16-14 UNC cap screw head. Power down or de-energize any equipment before performing fastener service on mechanical assemblies. Grade 8 fasteners should be paired with Grade 8 or equivalent-rated nuts and hardware to maintain rated load capacity. Follow applicable mechanical and structural codes for torque requirements based on the specific application and joint design.
