Value Collection BT-1213-500-AS Set Screw 1/2-13 X 1/2

Product Description

The VALUE COLLECTION BT-1213-500-AS is a 1/2-13 x 1/2 inch set screw with a soft tip point, manufactured from Grade 8 alloy steel with a brass tip insert. Set screws of this type are used to secure a component — such as a pulley, collar, or sprocket — onto a shaft without a protruding head. The hex drive socket accepts a standard hex key for installation and removal. The brass tip protects the mating surface from damage while still providing reliable holding force. This screw follows UNC and UNF thread standards and is suited for industrial and mechanical assembly work across trades.

This set screw is appropriate for general industrial, HVAC, and mechanical maintenance applications where shaft-mounted components require positive retention. The soft brass tip is commonly used in situations where surface marring of the shaft must be minimized, such as on precision shafts, motor shafts, or polished surfaces. It is installed by technicians and mechanics working on drive assemblies, fan hubs, couplings, and similar shaft-to-component connections. The 1/2-13 thread is a standard UNC coarse thread, and the 1/2 inch length is measured as the full thread length.

Key Features

• Grade 8 alloy steel construction provides high tensile and torsional strength
• Brass soft tip protects shaft surfaces from marring during tightening
• Hex drive socket compatible with standard hex keys and Allen wrenches
• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• Headless cup-free design sits flush or below the component surface
• Thread standard covers both UNC and UNF designations

Compatibility

Designed as a standard 1/2-13 UNC soft tip set screw for use in any tapped hole or threaded collar sized to accept a 1/2-13 thread. Suitable for shaft-retention applications in mechanical, HVAC, and industrial assemblies requiring a Grade 8 alloy steel fastener.

Installation Notes

Installation is performed using a hex key or Allen wrench sized to the internal hex drive socket. Ensure the mating threaded hole is clean and free of debris before driving the screw. De-energize or lock out any equipment before servicing shaft-mounted components to prevent injury. Do not exceed the rated torque range for a 1/2-13 Grade 8 fastener as specified by applicable mechanical standards.
