Value Collection 451151BR Hex Head Cap Screw 3/4-16 X 7 in Grade 8

Product Description

The VALUE COLLECTION 451151BR is a Grade 8 steel hex head cap screw with a 3/4-16 UNF thread and a 7-inch length under head. Manufactured to ASME B18.2.1 standards, this fastener delivers the high tensile strength required for heavy-duty bolted assemblies in industrial, mechanical, and structural applications. The partially threaded shank provides a smooth bearing surface in the grip area, which is critical for joints where shear loads are present. The bright, uncoated finish leaves the steel in its natural state, suitable for applications where coating is applied after assembly or where corrosion protection is handled separately. At 0.96 pounds, this screw is sized for demanding connections where smaller hardware grades are not appropriate.

This cap screw is used in heavy equipment assembly, machine frames, structural steel connections, and large mechanical assemblies that require a fine-threaded fastener capable of withstanding high clamp loads. The 3/4-16 UNF thread allows for tighter thread engagement and more precise torque control compared to coarse-thread equivalents. A 1-1/8-inch hex drive size means standard open-end, box-end, or socket wrenches used in trade and industrial shops are compatible. Grade 8 hardware is commonly specified in OEM machinery, agricultural equipment, and heavy transport component assemblies.

Key Features

• Grade 8 steel construction for high tensile and proof load requirements
• 3/4-16 UNF partially threaded shank with 7-inch length under head
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• Bright uncoated finish — no post-process coating to affect dimensional tolerances
• 1-1/8-inch hex key size compatible with standard trade wrenches and sockets
• Partially threaded design supports shear-load applications requiring a clean grip area

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application specifying a 3/4-16 UNF Grade 8 hex head cap screw conforming to ASME B18.2.1.

Installation Notes

Installation is performed by mechanical technicians, millwrights, or field service personnel using appropriately rated hand or power tools. Always verify the mating thread is undamaged and clean before assembly, and confirm the joint design calls for Grade 8 hardware before substituting lower-grade fasteners with this part. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for 3/4-16 UNF Grade 8 fasteners. Do not reuse fasteners that show signs of thread damage, stretching, or corrosion.
