Value Collection R57001175 Hex Head Cap Screw 9/16-12

Product Description

The VALUE COLLECTION R57001175 is a fully threaded hex head cap screw designed for general fastening applications where corrosion resistance is required. Made from 18-8 stainless steel with a bright, uncoated finish, this fastener measures 9/16-12 thread size with a 1-1/4 inch length under the head. The UNC (Unified National Coarse) thread standard ensures broad compatibility with standard tapped holes and nuts. This fastener is appropriate for use by mechanical contractors, millwrights, plumbers, and maintenance technicians working in corrosive or washdown environments where carbon steel fasteners are not suitable.

This screw is suited for light structural, mechanical, and equipment assembly tasks in residential, commercial, and industrial settings. The 18-8 stainless steel grade provides good resistance to oxidation and mild chemical exposure, making it a practical choice for HVAC equipment panels, pump assemblies, plumbing fixtures, and similar trade applications. Fully threaded construction allows the fastener to be used across a range of joint thicknesses without a grip-length limitation.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or mildly corrosive environments
• Fully threaded shank for maximum thread engagement across the entire fastener length
• UNC thread standard for compatibility with standard nuts, inserts, and tapped holes
• Bright, uncoated finish — no plating to degrade or introduce contamination concerns
• 9/16-12 thread size suits medium-duty structural and mechanical fastening needs

Compatibility

Designed as a standard UNC inch-series hex head cap screw for use with any 9/16-12 tapped hole, hex nut, or insert meeting ASME B18.2.1 dimensional standards.

Installation Notes

Installation requires a standard 7/8 inch hex wrench or socket. Ensure the mating tapped hole or nut is also stainless steel or a compatible alloy to prevent galvanic corrosion when used in wet environments. Apply appropriate anti-seize compound when joining stainless fasteners, as 18-8 stainless is susceptible to galling under high torque. Power down and de-energize any equipment before accessing fastened assemblies on live mechanical or electrical systems.
