Value Collection 701126PR Button Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 701126PR is a button socket cap screw designed for applications requiring a low-profile fastener head with a secure hex socket drive. Manufactured from alloy steel with a black oxide coating, it features a 5/16-18 UNC thread and measures 3-1/2 inches under the head. Hardness is rated at 36-43 HRC, making it suitable for moderate- to high-strength fastening tasks. The 3/16 inch hex socket drive is engaged with a standard hex key or T-handle driver. This screw is fully threaded and conforms to ANSI/ASME B18.3 and ASTM F835 standards.

This fastener is appropriate for mechanical assemblies, equipment enclosures, and structural bracketing where a flush or near-flush head profile is preferred. The black oxide finish provides light corrosion resistance and reduces surface glare, making it a common choice in industrial and mechanical maintenance environments. Machinists, millwrights, and general maintenance technicians typically install this type of screw where a standard hex cap screw head would interfere with adjacent components or covers.

Compatibility

Designed as a standard 5/16-18 UNC button socket cap screw for use in any tapped hole or threaded insert meeting ANSI/ASME B18.3 specifications for this thread size and drive type.

Installation Notes

Install using a 3/16 inch hex key or appropriately rated T-handle driver. Ensure the mating tapped hole is clean and free of debris before installation. Apply thread-locking compound if vibration is a concern in the application. Do not exceed the rated torque range for this thread size and hardness class as specified in applicable fastener standards.
