Value Collection KP44054 Hex Head Cap Screw 3/8-16 X 5 in Grade 8

Product Description

The VALUE COLLECTION KP44054 is a 3/8-16 hex head cap screw designed for heavy-duty fastening applications where high strength and corrosion resistance are required. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener delivers the tensile strength needed for demanding mechanical and structural assemblies. The partially threaded shank measures 5 inches in length under the head and follows the Unified National Coarse (UNC) thread standard. It meets ASTM A354 Grade BD specifications, making it a traceable, code-compliant choice for applications that require documented material standards. Licensed tradespeople and maintenance professionals rely on this grade for high-load connections.

This cap screw is suited for use in mechanical, industrial, and trade applications where a high-strength, zinc-plated fastener is required. The 3/8-16 UNC thread pattern is a common size across HVAC equipment frames, electrical enclosure mounting, plumbing support brackets, and general mechanical assembly. The partially threaded design allows for a smooth shank grip zone, which is beneficial when clamping two components together and preventing fastener rotation within the joint. Sold in packages of 25, this screw is appropriate for both service calls and larger installation projects requiring multiple identical fasteners.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile strength and traceability
• Zinc-plated finish provides corrosion resistance in exposed or moderately humid environments
• Partially threaded shank allows clamping force across unthreaded grip length
• 3/8-16 UNC thread standard ensures compatibility with standard nuts and tapped holes
• 5-inch length under head accommodates thicker material stacks and structural connections
• Package quantity of 25 supports multi-fastener installations and service stock

Compatibility

Designed as a standard UNC hex head cap screw for use with any 3/8-16 threaded nut or tapped hole requiring a Grade 8, ASTM A354 BD-compliant fastener in inch measurements.

Installation Notes

Installation should be performed by a qualified mechanic or trade professional using the appropriate 9/16-inch hex socket or wrench for the 3/8-16 head size. Always ensure the mating nut or tapped hole is also rated for Grade 8 loads before applying full torque. De-energize and isolate any equipment before fastening components near electrical or pressurized systems. Do not mix Grade 8 hardware with lower-grade nuts, as mismatched grades can lead to fastener failure under load.
