Value Collection 201013PR Button Socket Cap Screw

Product Description

The VALUE COLLECTION 201013PR is a button socket cap screw designed for precision fastening applications in mechanical assemblies, tooling, and fabricated components. The screw features a 3-48 UNC thread with a 3/16 inch length under the head and is fully threaded from tip to underhead. It is driven by a 1/16 inch hex socket. Manufactured from alloy steel with a black oxide coating, the 201013PR delivers hardness in the 36 to 43 HRC range and a Class 3A thread fit for tight dimensional tolerance. Licensed HVAC technicians, machinists, and maintenance professionals commonly use this fastener where a low-profile button head and high tensile strength are required.

This button socket cap screw is suited for use in machine components, enclosures, brackets, and assemblies where clearance above the fastener is limited and a flush or near-flush profile is needed. The black oxide finish provides moderate corrosion resistance and reduces light reflection, making it appropriate for interior mechanical environments. The fully threaded shank allows engagement through the full grip length. Minimum order quantity is 100 pieces per order, with individual package quantity of 1.

Key Features

• Button head profile for low-clearance fastening applications
• 3-48 UNC fully threaded shank with Class 3A thread fit
• Alloy steel construction with hardness rated 36 to 43 HRC
• Black oxide coating for moderate corrosion resistance and low reflectivity
• 1/16 inch hex socket drive for precise torque application in tight spaces
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 3-48 UNC button socket cap screw suitable for threaded holes conforming to ANSI/ASME B18.3 specifications in mechanical assemblies and fabricated components.

Installation Notes

Installation requires a 1/16 inch hex key or hex socket bit driver. Ensure mating threaded holes are clean and free of debris before driving the fastener to avoid cross-threading. Apply consistent torque appropriate for the alloy steel material grade and assembly requirements. Do not use impact tools on fine-pitch small-diameter screws, as this may damage the socket drive or strip the thread.
