Value Collection MP39061 Hex Cap Screw 3/8-16 Grade 8 10-pack

Product Description

The VALUE COLLECTION MP39061 is a 3/8-16 x 2-3/4 inch hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 is among the highest-strength classifications for inch-series fasteners, making this screw suitable for high-load structural and mechanical assemblies. The partial threading allows the unthreaded shank to bear shear loads, which is critical in bolted joints where lateral forces are present. Supplied in a pack of 10, this fastener conforms to ASME B18.2.1 dimensional standards and uses a UNC (Unified National Coarse) thread form.

This cap screw is used across a wide range of industrial, mechanical, and trade applications including HVAC equipment frames, pump mounting, compressor assemblies, structural steel connections, and general mechanical fabrication. The zinc yellow dichromate coating provides corrosion resistance suitable for indoor and light-duty outdoor environments. Electricians, millwrights, HVAC technicians, plumbers, and general contractors will encounter this fastener class in equipment installation and structural mounting tasks.

Key Features

• Grade 8 steel construction for high tensile strength in demanding mechanical joints
• 3/8-16 UNC thread form — widely compatible with standard inch-series nuts and tapped holes
• Partially threaded shank provides shear load capacity at the bolt bearing surface
• Zinc yellow dichromate finish offers corrosion resistance for general-duty applications
• Meets ASME B18.2.1 dimensional standards for consistent fit and interchangeability
• Sold in a pack of 10 with a minimum order quantity of 1 pack

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/8-16 UNC nuts, threaded inserts, and tapped holes conforming to ASME B18.2.1 specifications.

Installation Notes

Install using an appropriate hex socket or open-end wrench sized for a 3/8 inch hex head cap screw. Ensure mating threads and tapped holes are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant structural codes for Grade 8 fasteners. Do not substitute a lower-grade fastener in applications specified for Grade 8.
