Value Collection R57001280 Hex Cap Screw 3/4-16 X 3 in 18-8 Ss

Product Description

The VALUE COLLECTION R57001280 is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. Manufactured from 18-8 stainless steel with an uncoated finish, this fastener provides reliable corrosion resistance in wet, humid, or mildly corrosive environments. The screw features a 3/4-16 Unified National Fine (UNF) thread and measures 3 inches under the head. Partial threading allows for a smooth shank section, which is useful when clamping materials together without threading through the entire grip length. Tradespeople, maintenance technicians, and fabricators working with stainless hardware will find this fastener suited to a broad range of assembly tasks.

This hex head cap screw is appropriate for use in residential and commercial mechanical assemblies, HVAC equipment mounting, plumbing fixture attachment, pool equipment frameworks, and general industrial fabrication. The fine UNF thread pitch offers tighter thread engagement and is commonly preferred where vibration resistance or precise torque control is required. The 18-8 stainless steel grade makes it a practical choice in outdoor or moisture-prone installations where carbon steel fasteners would be prone to rust or staining.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and humid environments
• 3/4-16 UNF thread offers fine pitch for improved vibration resistance and thread engagement
• Partially threaded shank allows clean clamping action through unthreaded grip sections
• Uncoated finish — no plating or coating to flake, chip, or introduce galvanic concerns with stainless mating hardware
• 3-inch length under head accommodates moderate stack heights in structural and mechanical assemblies

Compatibility

Designed as a standard inch-series hex head cap screw for use with 3/4-16 UNF threaded holes, nuts, and inserts in any application requiring an 18-8 stainless steel fastener of this thread size and length.

Installation Notes

Install using a properly sized hex wrench or socket — 3/4-inch hex drive hardware typically requires a 1-1/8 inch or 1-3/16 inch wrench depending on the fastener standard; confirm the correct drive size before installation. Ensure mating threads are clean and free of debris before engagement to avoid cross-threading or galling, which is a known risk with stainless steel fasteners. Apply an appropriate anti-seize compound compatible with stainless steel if the fastener may need to be removed in the future. Follow applicable mechanical codes or equipment manufacturer torque specifications when installing in structural or pressure-bearing assemblies.
