Value Collection 451238BR Hex Head Cap Screw 3/4-10 X 15 in

Product Description

The VALUE COLLECTION 451238BR is a Grade 8 steel hex head cap screw designed for heavy-duty fastening applications. Measuring 3/4-10 thread size with a 15-inch length under head, this fastener features a partially threaded shank and an uncoated bright finish. Conforming to ASME B18.2.1 standards, it is produced to tight dimensional tolerances appropriate for structural and mechanical assemblies where high tensile strength is required. Weighing 1.94 pounds, this is a substantial fastener suited for industrial, construction, and heavy equipment work performed by maintenance technicians, millwrights, and mechanical contractors.

This hex head cap screw is used in applications requiring a UNC (Unified National Coarse) thread form with high clamping force. The partial thread configuration is typical for bolted joint assemblies where the shank bears shear loads and the threaded portion engages a nut or tapped hole. Common install scenarios include structural steel connections, heavy machinery frames, agricultural equipment, and large fabricated assemblies. A 1-1/8 inch hex key or wrench drive size is required for installation and removal.

Key Features

• Grade 8 steel construction provides high tensile and proof load strength for demanding structural applications
• 3/4-10 UNC thread form with 15-inch length under head suits long-reach bolting requirements
• Partially threaded shank design supports shear load transfer in bolted assemblies
• Bright uncoated finish — suitable for indoor or protected environments where coating is not required
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability
• 1-1/8 inch hex drive size compatible with standard impact wrenches and torque wrenches

Compatibility

Designed as a standard ASME B18.2.1 inch-series hex head cap screw; fits any application calling for a 3/4-10 UNC partially threaded fastener with a 15-inch length under head and Grade 8 minimum strength requirements.

Installation Notes

Installation should be performed by qualified mechanical technicians or tradespeople familiar with proper bolted joint procedures. Always de-energize and lock out equipment before replacing structural fasteners. Use a calibrated torque wrench to achieve the correct clamp load for the joint specification — do not rely on impact alone for final torque. Grade 8 fasteners should be replaced with Grade 8 or higher equivalents; substituting lower-grade hardware in structural joints is a safety hazard.
