Value Collection 93124 Button Cap Screw 5/16-18 3/4 in 18-8 Ss

Product Description

The VALUE COLLECTION 93124 is a button socket cap screw designed for applications requiring a low-profile head and strong clamping force. It features a 5/16-18 UNC thread and measures 3/4 inches in length under the head. The button-style head is driven by a 3/16-inch hex socket, making installation straightforward in tight clearance situations. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener resists corrosion in mildly harsh environments. It conforms to ANSI/ASME B18.3 and ASTM F837 standards, making it suitable for precision and structural fastening tasks across mechanical, HVAC, plumbing, and electrical enclosure assemblies.

This screw is used in a wide range of light to medium-duty fastening applications where a smooth, rounded head profile is needed to reduce snagging or provide a finished appearance. Common install scenarios include securing panels, brackets, and covers in residential and commercial mechanical systems. The right-hand, Class 3A thread fit ensures consistent engagement with standard UNC-threaded holes or nuts. Installers working in corrosive or moisture-prone environments often choose 18-8 stainless for its balance of corrosion resistance and machinability.

Key Features

• Button head profile provides low clearance and a clean finished look
• 5/16-18 UNC right-hand thread with Class 3A fit for reliable engagement
• 3/16-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction with bright uncoated finish for corrosion resistance
• Meets ANSI/ASME B18.3 and ASTM F837 fastener standards
• Head height of 0.166 inches for minimal protrusion above mating surface

Compatibility

Designed as a standard UNC replacement or service fastener for any application requiring a 5/16-18 button socket cap screw per ANSI/ASME B18.3 specifications.

Installation Notes

Install using a 3/16-inch hex key or socket bit driver. Ensure the mating thread is clean and free of debris before installation. Do not overtighten stainless steel fasteners, as galling can occur; applying an anti-seize compound is common practice. Always follow applicable mechanical or structural codes for the system being serviced.
