Value Collection 93129 Button Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 93129 is a 5/16-18 button socket cap screw designed for applications requiring a low-profile fastener head with reliable hex socket drive engagement. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw delivers solid corrosion resistance in both indoor and outdoor environments. The fully threaded, 2-inch length under head provides consistent grip across the full fastener shank. Thread fit class 3A ensures a precise, controlled fit with standard UNC nuts and tapped holes. This fastener is installed using a 3/16-inch hex socket key and is commonly used by mechanical contractors, millwrights, equipment fabricators, and maintenance technicians across a range of industrial and commercial applications.

This button socket cap screw suits applications where a standard hex cap head would interfere with adjacent components or where a smoother, rounded head profile is required. Typical use cases include machinery guards, enclosures, sheet metal assemblies, brackets, and light structural connections. The right-hand thread direction and UNC thread standard make this screw compatible with the most commonly available tapped holes and hex nuts in North American trade work. Sold individually with a minimum order quantity of 50 pieces per order.

Key Features

• Low-profile button head reduces interference in tight clearance assemblies
• 18-8 stainless steel construction provides corrosion resistance without surface coating
• 3/16-inch hex socket drive for reliable torque transfer with standard Allen keys or hex bit drivers
• Fully threaded 2-inch shank for maximum thread engagement across the fastener length
• Thread fit class 3A meets ANSI/ASME B18.3 and ASTM F837 fastener standards
• Right-hand UNC thread matches standard North American tapped holes and hardware

Compatibility

Designed for use with standard 5/16-18 UNC tapped holes and hex nuts conforming to ANSI/ASME B18.3 specifications. Suitable as a direct replacement or new installation fastener in any application requiring a 5/16-18 UNC button socket cap screw in 18-8 stainless steel.

Installation Notes

Installation requires a 3/16-inch hex key or hex socket bit driver. Confirm the tapped hole thread standard is UNC before installation to avoid cross-threading. De-energize and lock out any equipment before accessing fastener locations on live machinery, following applicable OSHA lockout/tagout procedures. Do not exceed the fastener's rated load by substituting this screw in structural applications for which it was not specified.
