Value Collection 39014 Hex Head Cap Screw 1/4-20 X 4 in Grade 8

Product Description

The VALUE COLLECTION 39014 is a 1/4-20 UNC hex head cap screw sized at 4 inches under the head, manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 steel provides high tensile strength suitable for demanding fastening applications in mechanical, industrial, and structural assemblies. The partial threading leaves a smooth shank section near the head, which helps maintain shear strength and alignment in bolted joints. This fastener conforms to ASME B18.2.1 dimensional standards and is sold in a package quantity of 50. It is installed using standard hex or socket tooling and is appropriate for trade professionals working in maintenance, fabrication, and equipment assembly.

This cap screw is suited for general industrial and mechanical applications where a high-strength inch-series fastener is required. The zinc yellow dichromate finish provides a baseline level of corrosion resistance for indoor and light-duty outdoor environments. Typical use cases include machinery assembly, structural bracketing, and equipment mounting where Grade 8 strength ratings and ASME B18.2.1 compliance are specified. The partial thread design is commonly selected when the joint requires a defined grip length.

Key Features

• Zinc yellow dichromate finish for corrosion resistance
• Partially threaded shank per ASME B18.2.1 dimensional standard
• 1/4-20 UNC thread form, 4 inches under head
• Sold in a package of 50 fasteners

Compatibility

Designed as an OEM-style replacement or general-use hex head cap screw for applications specifying 1/4-20 UNC Grade 8 fasteners conforming to ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician using a properly sized hex wrench or socket. Always verify the mating thread and torque specification from the equipment manufacturer before installation. Do not mix Grade 8 fasteners with lower-grade nuts or hardware, as mismatched grades can compromise joint integrity. Inspect threads for damage before installation and replace any fastener showing corrosion or deformation.
