Value Collection KP44050 Hex Cap Screw 3/8-16 Grade 8 50pk

Product Description

The VALUE COLLECTION KP44050 is a Grade 8 steel hex head cap screw sized 3/8-16 x 3-1/2 inches, designed for high-strength fastening applications in mechanical, structural, and industrial assemblies. The partially threaded shank provides a smooth bearing surface under the head, which helps maintain clamping force and reduces the risk of thread damage in through-bolt applications. A zinc-plated finish offers basic corrosion resistance in dry or mildly humid environments. These screws conform to ASTM A354 BD standards and ship in a package of 50 units, making them a practical stock item for service vans or shop inventory.

Grade 8 hex head cap screws like the KP44050 are commonly used in HVAC equipment mounting, electrical panel and enclosure assembly, mechanical supports, and structural bracketing where high tensile and proof-load strength is required. The 3/8-16 UNC thread size is one of the most widely used fastener sizes across trade and light industrial work. These screws are appropriate for use in both residential and light commercial applications wherever a high-strength, partially threaded fastener is called for.

Key Features

• Grade 8 steel construction meets ASTM A354 BD requirements for high tensile strength
• 3/8-16 UNC thread pattern for compatibility with standard nuts and tapped holes
• Partially threaded shank provides a smooth bearing zone under the head
• Zinc-plated finish for basic corrosion protection in dry service environments
• 3-1/2 inch length under head suits a range of through-bolt and deep-clearance applications
• Sold in a 50-unit pack for convenient stocking and job-site use

Compatibility

Designed as a standard 3/8-16 UNC Grade 8 hex head cap screw for use wherever ASTM A354 BD fasteners are specified in mechanical, structural, or equipment-mounting applications.

Installation Notes

Installation is appropriate for mechanics, HVAC technicians, electricians, and general tradespeople using standard hand or power tools with a 9/16-inch hex drive. Always de-energize equipment and relieve any system pressure before disassembling or reassembling fastened components. Pair with a Grade 8 or equivalent hardened flat washer and hex nut for full-strength assemblies. Do not substitute Grade 8 fasteners into assemblies specified for a lower grade without verifying design requirements.
