Value Collection MP39011 Hex Head Cap Screw 1/4-20 2-3/4 in Grade 8

Product Description

The VALUE COLLECTION MP39011 is a 1/4-20 UNC hex head cap screw manufactured from Grade 8 steel with a zinc yellow dichromate finish. At 2-3/4 inches in length under the head and partially threaded, this fastener delivers the high tensile strength and corrosion resistance required in demanding mechanical and structural assemblies. It conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for applications where specification compliance is required. Sold in a package of 25 pieces, it is well suited for maintenance stock, production runs, and field repair kits.

This hex head cap screw is used in general industrial, mechanical, and structural fastening applications where Grade 8 strength is specified. The partial threading provides a smooth shank section, which is beneficial in applications requiring a bearing surface or where shear loading is a factor. Typical installers include millwrights, maintenance technicians, and mechanical contractors working on equipment assemblies, machinery frames, and structural connections that call for inch-series UNC fasteners.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish provides corrosion and oxidation resistance
• Partially threaded shank allows for a smooth bearing surface under load
• 1/4-20 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• Conforms to ASME B18.2.1 dimensional standards
• Sold as a 25-piece package for stock and production use

Compatibility

Designed for use with standard 1/4-20 UNC inch-series hex nuts, lock nuts, and tapped components in general industrial and mechanical fastening applications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel using an appropriately sized hex wrench or socket driver. Ensure mating threads in nuts or tapped holes are clean, undamaged, and of compatible UNC thread form before assembly. Follow applicable torque specifications from the equipment manufacturer or relevant structural standards for Grade 8 fasteners. Do not mix inch-series and metric fasteners in the same threaded connection.
