Value Collection 208921 Hex Cap Screw 3/4-10 Unc 6.5 in

Product Description

The VALUE COLLECTION 208921 is a hex head cap screw designed for structural and mechanical fastening applications requiring corrosion-resistant hardware. Sized at 3/4-10 UNC with a 6.5-inch length under head, this screw is partially threaded and manufactured from Grade 18-8 stainless steel with no coating applied. The 1.125-inch hex drive head accepts a standard hex wrench or socket. At 0.7 pounds, this is a substantial fastener suited for heavy-duty assemblies in environments where moisture, chemicals, or outdoor exposure make carbon steel hardware unsuitable. Machinists, millwrights, pipefitters, and general maintenance trades install fasteners of this type across a wide range of industrial and mechanical applications.

This cap screw is appropriate for use in wet, marine, food-service, or chemically active environments where 18-8 stainless steel provides adequate corrosion resistance. The partial thread design allows the unthreaded shank to act as a shoulder, providing precise alignment and shear strength between mated components. Typical applications include equipment frames, flanged connections, machinery guards, structural brackets, and pump or blower assemblies. The 3/4-10 UNC thread form is a coarse-thread designation compatible with standard UNC-tapped holes and nuts of the same spec.

Key Features

• 3/4-10 UNC coarse thread form for compatibility with standard UNC tapped holes and nuts
• 6.5-inch length under head with partial threading for shank alignment and shear load transfer
• Grade 18-8 stainless steel construction for corrosion resistance in wet and chemically active environments
• Uncoated finish — no plating or coating that can flake, chip, or introduce galvanic incompatibility with stainless nuts
• 1.125-inch hex head accepts standard hex sockets and open-end wrenches
• Single-piece packaging with a minimum order quantity of one

Compatibility

Designed for use in any application requiring a 3/4-10 UNC hex head cap screw with a 6.5-inch length under head in Grade 18-8 stainless steel. Compatible with standard UNC 3/4-10 tapped holes, hex nuts, and washers of the same thread specification.

Installation Notes

Installation should be performed by a qualified mechanic or millwright following the applicable equipment manufacturer torque specifications for 3/4-10 UNC stainless fasteners. De-energize or lock out any equipment before replacing fasteners in mechanical assemblies. Apply an anti-seize compound rated for stainless steel threads to prevent galling, which is a common failure mode when torquing stainless fasteners against stainless nuts. Inspect mating threads for damage or contamination before assembly.
