Value Collection 403266BR Hex Head Cap Screw 3/4-10

Product Description

The VALUE COLLECTION 403266BR is a fully threaded hex head cap screw designed for general-purpose fastening in industrial, mechanical, and construction applications. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener measures 3/4-10 thread size with a 1-3/4 inch length under head. The zinc coating provides basic corrosion resistance in dry to mildly humid environments. It is driven with a 1-1/8 inch hex key or wrench and follows Unified National Coarse (UNC) thread standards. This screw is a staple for maintenance technicians, millwrights, pipefitters, and general contractors working on structural assemblies, equipment mounting, and mechanical connections.

This fastener is suited for residential, commercial, and light industrial settings where UNC-threaded connections are specified. Common applications include machinery assembly, HVAC equipment mounting, pipe support framing, electrical enclosure hardware, and general structural fastening. The fully threaded shank provides consistent thread engagement throughout the grip length, making it well-suited for shorter clamping distances and through-bolted joints.

Key Features

• Fully threaded shank for consistent engagement along the full 1-3/4 inch length under head
• Grade 2 steel construction for general-purpose tensile strength requirements
• Zinc-plated finish for basic corrosion resistance in dry to mildly humid conditions
• 3/4-10 UNC thread standard ensures compatibility with standard UNC-threaded nuts and tapped holes
• 1-1/8 inch hex drive fits standard open-end, box-end, and socket wrenches
• Inch measurement system for use in standard (non-metric) fastener applications

Compatibility

Designed for use with standard 3/4-10 UNC threaded nuts, washers, and tapped holes in inch-system fastener applications across mechanical, structural, and equipment-mounting assemblies.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or trade professionals using a standard 1-1/8 inch open-end, box-end, or socket wrench. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or anti-seize as required by the application or applicable torque specifications from the equipment manufacturer. Torque to values specified in project drawings or equipment documentation — do not substitute generic torque figures without engineering guidance.
