Value Collection 201016PR Button Socket Cap Screw 3-48

Product Description

The VALUE COLLECTION 201016PR is a fully threaded button socket cap screw designed for compact fastening applications where a low-profile head is required. It features a 3-48 UNC thread with a right-hand thread direction and a 1/16-inch hex socket drive. The alloy steel construction is finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection. Hardness is rated at 36-43 HRC, meeting the mechanical requirements of ANSI/ASME B18.3 and ASTM F835. This fastener is installed by machinists, maintenance technicians, and assembly professionals using a 1/16-inch hex key.

This screw is suited for light-duty machine assembly, instrument enclosures, and precision mechanical assemblies where a flush or near-flush head profile is needed. The button head style distributes clamping load over a wider bearing area than a standard socket cap screw, making it appropriate for softer substrates or thinner materials. It is commonly used in industrial maintenance, electronics assembly, and mechanical fabrication environments.

Key Features

• Button head style with 1/16-inch hex socket drive for low-profile installations
• 3-48 UNC fully threaded, right-hand thread direction
• Alloy steel construction with 36-43 HRC hardness rating
• Black oxide finish for mild corrosion resistance and reduced reflectivity
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards
• Thread fit class 3A for consistent tolerance and fit

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for applications requiring a 3-48 UNC button socket cap screw with a 1/2-inch length under head.

Installation Notes

Installation requires a 1/16-inch hex key or Allen driver. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Do not exceed the torque capacity appropriate for the 3-48 thread size and alloy steel material grade. Always de-energize and lock out any equipment before performing fastener service on mechanical assemblies.
