Value Collection MPKP44046 Hex Cap Screw 3/8-16 X 2-1/2 in Grade 8

Product Description

The VALUE COLLECTION MPKP44046 is a partially threaded hex head cap screw designed for high-strength fastening applications in mechanical, structural, and industrial assembly work. Built to Grade 8 steel specifications and certified to ASTM A354 BD, this fastener delivers the tensile strength required for demanding load-bearing connections. The 3/8-16 UNC thread profile and 2-1/2-inch length under head make it a common choice for framing fixtures, equipment mounting, and heavy-duty mechanical assemblies. A zinc-plated finish provides baseline corrosion resistance suitable for dry and low-moisture environments. Sold in a pack of 25 units.

This fastener is suited for residential and commercial maintenance, equipment installation, and fabrication work performed by millwrights, pipefitters, HVAC technicians, and general maintenance trades. The partial threading allows for a smooth shank section that resists shear forces in applications where bolt grip length matters. Typical use cases include mounting brackets, flanges, and structural steel connections where a Grade 8 rated fastener is specified by the engineer or equipment manufacturer.

Key Features

• Grade 8 steel construction meets ASTM A354 BD standard for high tensile and proof load strength
• 3/8-16 UNC thread size with partial threading for shear-resistant installations
• 2-1/2-inch length under head for deeper fastening reach
• Zinc-plated finish for basic corrosion protection in dry service environments
• Pack of 25 units reduces per-fastener cost on multi-bolt applications

Compatibility

Designed as a standard 3/8-16 UNC hex head cap screw compatible with any application requiring a Grade 8 partially threaded fastener at 2-1/2 inches length under head per ASTM A354 BD specifications.

Installation Notes

Installation should follow torque specifications published by the equipment manufacturer or applicable structural standards for Grade 8 fasteners at this thread size. Always use the correct hex socket or wrench to avoid rounding the head. Ensure mating threads are clean and free of debris before installation. Do not substitute a lower-grade fastener in any application specifying Grade 8.
