Value Collection 701227BR Button Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION 701227BR is a fully threaded button socket cap screw designed for mechanical assemblies where a low-profile head and high clamping strength are required. Built from alloy steel with a black oxide coating, it resists corrosion and reduces light reflection in finished assemblies. The screw measures 5/8-11 thread size by 3 inches in length under the head, driven by a 3/8-inch hex socket. It conforms to ANSI/ASME B18.3 and ASTM F835 standards with a 3A thread fit class and right-hand thread direction. Hardness is rated at 36-43 HRC. Machinists, millwrights, and general industrial mechanics use this fastener regularly.

This button socket cap screw suits applications where a smooth, rounded head profile is necessary to avoid snagging or for aesthetic fit in exposed assemblies. Common install scenarios include machine frames, fixtures, guards, and enclosures in both light manufacturing and heavy industrial environments. The UNC thread standard makes it compatible with standard inch-system tapped holes. The black oxide finish is appropriate for interior or low-moisture environments where a clean, matte appearance is preferred over a plated finish.

Key Features

• Button head profile provides low-profile, snag-free surface for exposed assemblies
• Alloy steel construction with 36-43 HRC hardness for high-strength clamping
• Black oxide coating reduces surface reflection and provides mild corrosion resistance
• 3/8-inch hex socket drive for standard L-key or socket-head tooling
• Fully threaded 5/8-11 UNC right-hand thread, 3A fit class for precise engagement
• Meets ANSI/ASME B18.3 and ASTM F835 dimensional and mechanical standards

Compatibility

Designed for use in standard inch-system 5/8-11 UNC tapped holes in alloy steel, mild steel, aluminum, or other structural materials where button socket cap screws conforming to ANSI/ASME B18.3 are specified.

Installation Notes

Installation requires a 3/8-inch hex key or socket-head driver rated for the torque demands of a 5/8-11 fastener. Verify that the mating tapped hole is clean, properly formed to UNC 5/8-11 specification, and free of debris before driving. Do not exceed recommended torque for the material being fastened to avoid thread stripping or fastener failure. The black oxide finish does not provide heavy corrosion protection — apply a supplemental lubricant or thread compound in wet or outdoor environments if required.
