Value Collection 307236BR Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION 307236BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. It features a 1-8 UNC thread size with a 3-inch length under head and is fully threaded from end to end. The screw is driven with a 5/8-inch hex key. Constructed from alloy steel with a black oxide finish coating, it delivers solid tensile strength and moderate corrosion resistance in controlled environments. This fastener meets ASTM A574 specifications, the standard governing alloy steel socket-head cap screws. Machinists, maintenance technicians, and industrial assemblers commonly install this type of fastener.

This hex socket cap screw is suited for use in machinery frames, jigs, fixtures, tooling plates, and general industrial assemblies where a recessed drive head and high clamp load are required. The 1-8 UNC coarse thread pitch is compatible with standard tapped holes and threaded inserts of the same specification. The black oxide finish provides a clean, low-reflectance appearance and light surface protection. Full threading along the 3-inch shank length gives flexibility in engagement depth across varying material thicknesses.

Key Features

• 1-8 UNC coarse thread for compatibility with standard tapped holes
• Fully threaded shank allows flexible engagement depth
• 5/8-inch hex drive for use with standard hex keys or Allen wrenches
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish provides light corrosion resistance and low reflectance

Compatibility

Designed as a direct-fit replacement or standard-stock fastener for any application requiring a 1-8 UNC hex socket cap screw with a 3-inch length under head conforming to ASTM A574.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a calibrated torque wrench and the appropriate 5/8-inch hex key or socket drive. Verify that the receiving tapped hole is clean and meets 1-8 UNC thread specifications before installation. Apply thread lubricant or anti-seize as required by the assembly specification. Do not exceed the rated torque for the fastener grade as defined by ASTM A574 or the equipment manufacturer.
