Value Collection 93127 Button Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 93127 is a 5/16-18 button socket cap screw designed for fastening applications that require a low-profile head and reliable corrosion resistance. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw delivers solid mechanical performance in wet or chemically exposed environments. The hex socket drive accepts a 3/16 inch hex key for installation and removal. At 1-1/2 inches length under head and fully threaded along its shank, it provides consistent thread engagement across the full fastened length. Conforming to ANSI/ASME B18.3 and ASTM F837 standards, it meets the dimensional and mechanical requirements expected in trade and industrial use.

This fastener is suited for mechanical assemblies, equipment mounting, and structural connections where a button-head profile is preferred over a standard cap screw head. The UNC thread form and 3A thread fit class make it compatible with standard unified inch tapped holes. Typical applications include HVAC equipment frames, plumbing fixture brackets, electrical enclosures, and general mechanical assemblies where stainless steel corrosion resistance is a requirement. Installation is performed by tradespeople and maintenance technicians using standard hex keys or hex-bit drivers.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and chemically exposed environments
• Button head profile offers a low-profile, smooth appearance with reduced snag risk
• 3/16 inch hex socket drive for use with standard Allen keys or hex-bit drivers
• Fully threaded shank for maximum thread engagement at 1-1/2 inches length under head
• 3A thread fit class ensures precise fit in standard UNC tapped holes
• Meets ANSI/ASME B18.3 and ASTM F837 dimensional and mechanical standards

Compatibility

Designed as a standard UNC 5/16-18 button socket cap screw for use in any application requiring ANSI/ASME B18.3-compliant fasteners with a 3/16 inch hex socket drive and 18-8 stainless steel material.

Installation Notes

Install using a properly sized 3/16 inch hex key or hex-bit driver to avoid rounding the socket drive. Verify that the mating tapped hole conforms to UNC 5/16-18 thread specifications before installation. Apply thread-locking compound or stainless-compatible anti-seize as required by the application to prevent galling, which is common with stainless steel fasteners. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
