Value Collection MP39036 Hex Cap Screw 5/16-18 Grade 8 25pk

Product Description

The VALUE COLLECTION MP39036 is a 5/16-18 x 2-3/4 inch hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. Partially threaded along the shank, this fastener is built to handle high-strength bolted joint applications where tensile strength and shear resistance are critical. The hex drive head accepts standard wrenches and sockets. Conforming to ASME B18.2.1, it meets established dimensional standards for inch-series hex cap screws. Machinists, millwrights, mechanics, and industrial maintenance technicians regularly specify Grade 8 fasteners for heavy equipment, structural assemblies, and machinery where standard Grade 5 hardware is insufficient.

This fastener is suited for use in ferrous and non-ferrous structural connections, general mechanical assemblies, and equipment fabrication where a Unified National Coarse (UNC) thread form is required. The zinc yellow dichromate finish provides a base level of corrosion resistance suitable for indoor and light-duty outdoor environments. Sold in a package quantity of 25, this SKU is appropriate for shops, service trucks, and maintenance departments that need a reliable stock of high-strength inch-series hardware on hand.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 5/16-18 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• Partially threaded shank allows for precise clamping in bolted joint applications
• Zinc yellow dichromate finish provides corrosion resistance and visual identification
• Conforms to ASME B18.2.1 dimensional standards
• Package of 25 fasteners for shop stock and service use

Compatibility

Designed for use with standard 5/16-18 UNC inch-series nuts and tapped holes conforming to ASME and ANSI thread standards. Verify joint material, clamp load requirements, and finish suitability before installation.

Installation Notes

Installation is performed by mechanics, millwrights, and maintenance technicians using standard hex wrenches or sockets. Always clean and inspect the mating threads before installation to prevent cross-threading or galling. Do not mix Grade 8 fasteners with lower-grade nuts, as mismatched hardware can compromise joint integrity. Follow applicable industry standards and equipment manufacturer torque specifications for the joint being assembled.
