Value Collection 111567PR Set Screw 1/2-13 X 1/2 in Grade 8

Product Description

The VALUE COLLECTION 111567PR is a Grade 8 alloy steel set screw designed for secure, vibration-resistant fastening in mechanical assemblies. Featuring a knurled cup point, this fastener bites into mating surfaces to resist rotational and axial movement without requiring a through-hole. The 1/2-13 UNC thread and 1/2-inch overall length suit a wide range of mid-size clamping and locking applications. Drive is a 1/4-inch hex socket, compatible with standard hex keys and drivers. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, the part delivers consistent dimensional accuracy and mechanical performance expected in industrial and trade use.

This set screw is suited for use in shaft collars, pulleys, sprockets, gears, and similar components in industrial machinery, HVAC equipment, and mechanical drive systems. The knurled cup point is particularly effective when a permanent or semi-permanent hold is needed against a hardened or rough shaft surface. Minimum order quantity is 100 pieces per order. Individual package quantity is 1.

Key Features

• Knurled cup point bites into mating surfaces for strong rotational and axial resistance
• Grade 8 alloy steel construction for high tensile and torsional strength
• 1/2-13 UNC thread for broad compatibility with standard inch-series hardware
• 1/4-inch hex drive accepts standard hex keys and Allen-type drivers
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and mechanical standards
• Fractional inch sizing for straightforward specification and replacement

Compatibility

Designed as an OEM-style replacement or standard-stock set screw for applications requiring a 1/2-13 UNC, 1/2-inch overall length, knurled cup point fastener in Grade 8 alloy steel.

Installation Notes

Installation is typically performed by a machinist, millwright, or qualified mechanical technician using a calibrated 1/4-inch hex key. De-energize and lock out all rotating equipment before installing or adjusting set screws. Do not exceed the torque capacity of the hex drive; use the correct key size to avoid socket rounding. Ensure the mating shaft surface is clean and free of burrs before seating the cup point.
