Value Collection D39171 Hex Cap Screw 3/4-10 X 1-3/4 Grade 8

Product Description

The VALUE COLLECTION D39171 is a fully threaded hex head cap screw intended for high-strength fastening applications across industrial, mechanical, and structural assembly work. It is manufactured from Grade 8 steel, which provides superior tensile and yield strength compared to lower-grade fasteners. The 3/4-10 thread designation indicates a 3/4-inch nominal diameter with 10 threads per inch on a Unified National Coarse (UNC) thread form. Overall length under the head measures 1-3/4 inches. The zinc yellow dichromate finish delivers a base level of corrosion resistance and is the standard identifier for Grade 8 hardware. Machinists, millwrights, fabricators, and maintenance technicians regularly specify this fastener for bolted joints subject to high static and dynamic loads.

This cap screw is suited for use in heavy equipment assembly, machine frames, structural steel connections, and general industrial maintenance where Grade 8 strength is required. The fully threaded shank allows engagement along the entire length under the head, making it well matched for through-bolting and shorter clamped joint configurations. The UNC thread form is compatible with standard 3/4-10 hex nuts and tapped holes per ASME B18.2.1 dimensional standards. It is sold in individual units with a minimum order quantity of 25 pieces.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Fully threaded shank along the full 1-3/4-inch length under head
• 3/4-10 UNC thread form for broad compatibility with standard nuts and tapped holes
• Zinc yellow dichromate finish provides baseline corrosion resistance and Grade 8 identification
• Conforms to ASME B18.2.1 dimensional standards
• Minimum order quantity of 25 units per order

Compatibility

Designed for use with standard 3/4-10 UNC hex nuts, flat washers, and lock washers in any bolted joint application requiring Grade 8 fastener strength per ASME B18.2.1.

Installation Notes

Installation is performed by qualified machinists, millwrights, or maintenance technicians using appropriate hand tools or power tooling with torque control. Always verify that the mating nut or tapped hole thread class matches before assembly. Follow the applicable equipment manufacturer torque specifications and joint design requirements for Grade 8 fasteners. Inspect threads for damage or contamination before installation and ensure joint members are properly aligned to avoid cross-threading.
