Value Collection 454525BR Hex Cap Screw 3/4-10 X 4-1/4 Grade 8

Product Description

The VALUE COLLECTION 454525BR is a 3/4-10 x 4-1/4 inch hex head cap screw manufactured from Grade 8 steel with a zinc-plated finish. Partially threaded along the shank, it conforms to ASME B18.2.1 dimensional standards for inch-series hex cap screws. The Unified National Coarse (UNC) thread profile provides reliable clamping force in high-strength bolted joints. This fastener is suited for demanding structural and mechanical assemblies where Grade 8 tensile strength is required. Installation requires a 1-1/8 inch hex wrench or socket. Tradespeople in mechanical, HVAC equipment mounting, and general industrial assembly applications will recognize this as a standard heavy-duty fastener.

This hex head cap screw is used in structural bolted connections, equipment frames, machinery mounting, and similar applications where a high-strength inch-series fastener is specified. The partial thread design maintains shank integrity across unthreaded bearing surfaces, making it appropriate for through-bolt installations with close-tolerance clearance holes. It is suitable for both shop fabrication and field assembly work.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc-plated finish provides baseline corrosion resistance
• Partially threaded shank suits through-bolt and close-tolerance applications
• UNC 3/4-10 thread form for broad nut and tapped-hole compatibility
• Meets ASME B18.2.1 dimensional standard for inch hex cap screws
• 1-1/8 inch hex drive size compatible with standard impact and hand sockets

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/4-10 UNC nuts, tapped holes, and threaded inserts in Grade 8 or compatible bolted joint specifications per ASME B18.2.1.

Installation Notes

Installation is performed with a 1-1/8 inch socket or box-end wrench. De-energize and lock out any equipment before fastening components in electromechanical assemblies. Apply fastener torque per the joint designer's specification for Grade 8 hardware — do not substitute torque values from this listing, as none are provided. Follow applicable codes such as AISC, ASME, or OEM torque tables for the specific joint application.
