Value Collection 242301 Button Socket Cap Screw 5/16-18 X 1

Product Description

The VALUE COLLECTION 242301 is a button socket cap screw designed for applications requiring a low-profile fastener with a clean, rounded head. Sized at 5/16-18 x 1 inch with a 3/16 inch hex socket drive, this screw is manufactured from 18-8 stainless steel with a bright, uncoated finish. The button head style reduces protrusion above the mating surface, making it well suited for assemblies where clearance is limited. It conforms to ANSI/ASME B18.3 and carries a 3A thread fit class with right-hand, Unified National Coarse threading. Licensed trades and maintenance professionals working with corrosion-resistant hardware will find this fastener appropriate for a wide range of mechanical assemblies.

This screw is used in light to medium-duty mechanical assemblies where a low-profile head and corrosion resistance are priorities. Common applications include equipment panels, enclosures, brackets, and machinery guards in both indoor and outdoor environments. The 18-8 stainless steel construction makes it suitable for humid or mildly corrosive conditions. It is a standard choice for HVAC equipment panels, electrical enclosures, pump housings, and similar trade hardware installations where a conventional hex cap screw head height would interfere with adjacent components or covers.

Key Features

• Button head profile keeps fastener protrusion low, ideal for tight-clearance assemblies
• 18-8 stainless steel construction resists corrosion in humid and mildly corrosive environments
• 3/16 inch hex socket drive for use with standard hex keys or Allen drivers
• 5/16-18 UNC thread at 3A fit class ensures consistent engagement and reliable clamping
• Bright, uncoated finish maintains dimensional accuracy and suits general industrial use
• Conforms to ANSI/ASME B18.3 for dimensional and material standardization

Compatibility

Designed as an OEM-style replacement or standard hardware fastener for mechanical assemblies requiring a 5/16-18 UNC button socket cap screw in 18-8 stainless steel per ANSI/ASME B18.3.

Installation Notes

Install and remove using a 3/16 inch hex key or Allen driver of appropriate quality to avoid rounding the socket. Power down or de-energize any equipment before accessing fastened assemblies on electrical or HVAC components. Do not over-torque stainless steel fasteners, as galling can occur; application of an anti-seize compound is common practice when assembling stainless hardware. Follow applicable codes and equipment manufacturer torque guidelines for the specific assembly.
