Value Collection 211370BR Flat Socket Cap Screw 3/4-10 X 2 in

Product Description

The VALUE COLLECTION 211370BR is a flat socket cap screw designed for flush or countersunk fastening applications in structural and mechanical assemblies. It features an 82-degree flat head profile with a 1/2-inch hex socket drive, allowing installation with a standard hex key or Allen wrench. Sized at 3/4-10 UNC x 2 inches overall length, the screw is fully threaded and manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and a low-reflectance appearance. This fastener meets ASME/ANSI B18.3 and ASTM F835 standards. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in equipment frames, fixtures, and fabricated assemblies.

This screw is suited for applications where the fastener head must sit flush with or below a mating surface. The 82-degree countersink angle is the standard for inch-series flat head socket cap screws, making it compatible with pre-machined or drilled countersink holes following ASME/ANSI B18.3 geometry. Typical use cases include machine tool components, conveyor frames, fixture plates, and similar industrial or commercial equipment where a recessed head is required to avoid interference with adjacent parts or moving components. The black oxide finish is appropriate for indoor or low-moisture environments.

Key Features

• 82-degree flat head profile seats flush in standard inch-series countersunk holes
• 1/2-inch hex socket drive for reliable torque transfer with a hex key
• 3/4-10 UNC thread size, 2 inches overall length, fully threaded
• Alloy steel construction for high tensile strength in structural fastening
• Black oxide finish reduces light reflection and offers mild corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard inch-series countersunk holes with an 82-degree included angle, conforming to ASME/ANSI B18.3 geometry. Suitable for 3/4-10 UNC tapped holes in steel, aluminum, and similar structural materials.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated hex key or Allen driver sized to the 1/2-inch drive socket. Ensure the mating countersink is machined to the correct 82-degree angle and appropriate depth before installation. De-energize or lock out any equipment before fastener replacement in live machinery per applicable OSHA lockout/tagout procedures. Do not exceed the fastener's rated torque specification as defined by the relevant ASME standard for this diameter and grade.
