Value Collection 201014PR Button Socket Cap Screw 3-48

Product Description

The VALUE COLLECTION 201014PR is a button socket cap screw designed for secure, low-profile fastening in tight-clearance assemblies. It features a 3-48 UNC thread with a 1/16-inch hex socket drive and a fully threaded shank measuring 1/4 inch under the head. Manufactured from alloy steel with a black oxide coating, it delivers hardness in the 36-43 HRC range for reliable clamping strength. The black oxide finish provides mild corrosion resistance and a consistent dark appearance suited for precision mechanical assemblies. This fastener meets ANSI/ASME B18.3 and ASTM F835 standards.

This screw is used in applications where a standard hex cap or pan-head screw would create interference with adjacent components. The button head profile reduces protrusion while maintaining a strong, clean seat. Typical installations include instrument panels, electronic enclosures, jigs and fixtures, and light mechanical assemblies. It is installed by machinists, maintenance technicians, and precision assembly workers who require a standardized, torque-rated fastener in confined spaces.

Key Features

• Button head profile minimizes protrusion for clearance-critical assemblies
• 3-48 UNC fully threaded shank with right-hand thread direction
• 1/16-inch hex socket drive for standard Allen key installation
• Alloy steel construction with 36-43 HRC hardness per ASTM F835
• Black oxide coating for mild corrosion resistance and consistent appearance
• Thread fit class 3A for precise, reliable engagement

Compatibility

Designed as a standard 3-48 UNC button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835, suitable for use in any application requiring a low-profile hex socket fastener in that thread size.

Installation Notes

Install with a calibrated 1/16-inch hex key or Allen driver. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Power down or de-energize any electrical or mechanical assembly before accessing fastener locations in live equipment. Do not exceed the torque capacity of the 3-48 thread form, and verify thread engagement depth meets design requirements before applying load.
