Value Collection 242300 Button Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 242300 is a button head socket cap screw designed for applications where a low-profile fastener head is required. Featuring a 5/16-18 UNC thread and a 3/16-inch hex socket drive, this screw is turned with a standard hex key or Allen wrench. Constructed from 18-8 stainless steel with a bright, uncoated finish, it resists corrosion in moderate-exposure environments. The 3/4-inch length under head suits a wide range of medium-duty mechanical assemblies. Manufactured to ANSI/ASME B18.3 standards, it is suited for use in fabrication, maintenance, and general industrial work performed by machinists, millwrights, and maintenance technicians.

This screw is used in applications where a standard hex cap screw head would protrude too far or interfere with adjacent components. The low-profile button head distributes clamping load across a wider bearing surface, making it a practical choice for sheet metal assemblies, equipment panels, jigs, and fixtures. The 18-8 stainless steel construction makes it appropriate for light outdoor exposure, food-adjacent equipment, and environments where mild corrosion resistance is needed. This fastener ships in a minimum order quantity of 100 pieces per the supplier specification.

Key Features

• Button head profile provides low clearance and wide bearing surface
• 18-8 stainless steel construction for moderate corrosion resistance
• 5/16-18 UNC right-hand thread, Class 3A fit for precise tolerancing

• Bright, uncoated finish — no additional surface treatment
• Manufactured to ANSI/ASME B18.3 fastener standard

Compatibility

Designed as an OEM-style and general-purpose replacement or new-install button socket cap screw for any application requiring a 5/16-18 UNC thread, 3/4-inch grip length, and ANSI/ASME B18.3 compliance.

Installation Notes

Installation is performed with a 3/16-inch hex key or hex socket bit driver. Ensure mating threads are clean and free of debris before driving. Do not overtighten stainless steel fasteners, as the material is susceptible to galling — apply an appropriate anti-seize compound when installing into stainless or aluminum tapped holes. Verify thread engagement and torque requirements against the assembly specification for the host equipment.
