Value Collection C52000697 Button Cap Screw 5/16-18 316 Ss

Product Description

The VALUE COLLECTION C52000697 is a fully threaded button socket cap screw designed for fastening applications where a low-profile head and high corrosion resistance are required. This screw features a 5/16-18 UNC thread with a 1-1/2 inch length under the head and a hex socket drive sized at 3/16 inch. Constructed from 316 stainless steel with a bright, uncoated finish, it is well suited for environments exposed to moisture, chemicals, or marine conditions. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, and related mechanical fields commonly use this fastener type when assembling brackets, panels, or equipment enclosures.

This button socket cap screw is appropriate for light to medium-duty fastening tasks in residential and commercial mechanical systems. Its button head profile keeps a low stance in confined spaces where clearance is limited. The UNC thread form and Class 3A thread fit ensure consistent engagement with standard tapped holes. It ships in a package quantity of 5, making it practical for single repairs or small assembly jobs. Installers working with stainless hardware in wet, coastal, or corrosive environments will find the 316 alloy grade a reliable choice over standard 18-8 stainless.

Key Features

• 316 stainless steel construction resists corrosion in harsh and marine environments
• Button head style provides a low-profile seating surface for clearance-restricted applications
• 3/16 inch hex socket drive accepts standard hex keys and socket bit drivers
• Fully threaded along the 1-1/2 inch shank length for maximum thread engagement
• Class 3A thread fit meets ANSI/ASME B18.3 fastener standard
• Bright, uncoated finish maintains dimensional accuracy without coating buildup in threaded holes

Compatibility

Designed as an OEM-style replacement or service fastener for any application requiring a 5/16-18 UNC fully threaded button socket cap screw in 316 stainless steel.

Installation Notes

Installation is performed with a 3/16 inch hex key or hex socket bit driver. Verify that the mating tapped hole is clean and free of debris before threading to prevent galling, which is common with stainless steel fasteners. Apply an anti-seize compound appropriate for stainless-to-stainless contact to reduce the risk of thread seizing. Follow applicable mechanical and equipment manufacturer torque guidelines for 5/16-18 hardware in the specific assembly.
