Value Collection MPKP44042 Hex Cap Screw 3/8-16 Grade 8 25pk

Product Description

The VALUE COLLECTION MPKP44042 is a 3/8-16 UNC hex head cap screw measuring 1-1/2 inches under the head, manufactured from Grade 8 steel with a zinc-plated finish. Grade 8 is among the highest strength classifications for inch-series fasteners, making this screw appropriate for high-load mechanical assemblies, equipment mounting, and structural connections. The partial threading provides a smooth shank section that resists shear stress in applications where the fastener passes through clearance holes before engaging a tapped bore or nut. This part is sold in a package quantity of 25. Sold individually by pack to authorized trade buyers at minimum order quantity of 1 pack.

This screw suits a broad range of trade and industrial installation scenarios, including HVAC equipment mounting, mechanical support structures, electrical panel supports, pump and motor bases, and general mechanical assemblies requiring high-strength inch-series hardware. The zinc plating provides a basic level of corrosion resistance appropriate for indoor and sheltered outdoor environments. The ASTM A354 BD designation confirms the fastener meets recognized standards for mechanical properties including tensile strength and proof load.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile strength and proof load requirements
• 3/8-16 UNC thread size, 1-1/2 inches under head for precise fit in standard tapped holes
• Partially threaded shank resists shear loads in clearance-hole applications
• Zinc-plated finish provides basic corrosion protection for sheltered environments
• Hex head drive accepts standard hex wrenches and socket sets common in trade work
• Packaged in quantities of 25 for efficient jobsite use

Compatibility

Designed for use in any application requiring a 3/8-16 UNC partially threaded hex head cap screw conforming to ASTM A354 BD Grade 8 specifications.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable mechanical or structural codes for the specific application. Always use the correct torque specification for Grade 8 fasteners as defined by the equipment manufacturer or relevant engineering standard — do not estimate by feel. Ensure the mating tapped hole or nut matches the 3/8-16 UNC thread specification before installation. Inspect threads for damage before use and do not reuse fasteners that show signs of stretching or corrosion.
