Value Collection D39102 Hex Head Cap Screw 1/2-13 X 3/4 in Grade 8

Product Description

The VALUE COLLECTION D39102 is a fully threaded hex head cap screw sized 1/2-13 x 3/4 inches, manufactured from Grade 8 steel with a zinc yellow dichromate finish. Grade 8 is a high-strength fastener classification, suited for demanding structural and mechanical assemblies where shear and tensile loads are a concern. The zinc yellow dichromate coating provides corrosion resistance while meeting ASME B18.2.1 dimensional standards. This screw is used by millwrights, pipefitters, electricians, and general contractors who require reliable, code-dimensioned fasteners in fabrication and equipment installation work.

This fastener is appropriate for use in industrial, commercial, and residential mechanical assemblies. The 1/2-13 UNC thread is one of the most common coarse-thread sizes in trade applications, appearing in structural steel connections, bracket mounting, equipment bases, and panel attachments. The fully threaded configuration maximizes thread engagement across the entire shank length, which is useful when fastening thin materials or when full clamping force along the bolt length is required. This item is sold individually with a minimum order quantity of 25 pieces.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Zinc yellow dichromate finish for corrosion resistance
• Fully threaded shank for maximum thread engagement
• 1/2-13 UNC coarse thread — a widely used standard trade size
• Meets ASME B18.2.1 dimensional standards
• 3/4 inch length under head for compact fastening applications

Compatibility

Designed as a standard UNC hex head cap screw conforming to ASME B18.2.1, suitable for use in any mechanical or structural assembly that calls for a 1/2-13 x 3/4 inch Grade 8 fully threaded fastener.

Installation Notes

Installation of Grade 8 hex head cap screws typically requires a standard hex wrench or socket set. Always verify that the mating nut or tapped hole is rated for the same thread class and grade to avoid thread stripping. Follow applicable torque specifications from your equipment manufacturer or relevant codes such as AISC or ASME guidelines for structural bolting. Inspect threads for damage before installation and do not reuse fasteners that show deformation or corrosion.
