Value Collection 703458PR Set Screw 3/8-16 X 3/8 in Flat Point

Product Description

The VALUE COLLECTION 703458PR is a flat point set screw designed for secure, low-profile fastening in mechanical assemblies where a projecting fastener head is not acceptable. Threaded to the 3/8-16 UNC standard and measuring 3/8 inches in overall length, this screw is driven with a 3/16-inch hex key. It is manufactured from austenitic stainless steel Grade A2, providing solid corrosion resistance in wet or chemically active environments. Machinists, millwrights, and maintenance technicians install this type of fastener to lock collars, pulleys, gears, and similar components to shafts without protruding hardware.

This set screw is suited for general industrial, HVAC, plumbing, and mechanical maintenance applications where a UNC 3/8-16 threaded hole is present. The flat point distributes clamping load across the shaft surface, reducing indentation on hardened or finished shafts. It conforms to ASME/ANSI B18.3 and ASTM F880 standards, making it appropriate for use in code-sensitive assemblies. It is sold individually but carries a minimum order quantity of 10 pieces, typical for commercial fastener procurement.

Key Features

• 3/8-16 UNC thread form for wide compatibility with standard threaded bores
• 3/8-inch overall length for shallow-depth fastening applications
• Flat point design minimizes shaft surface damage and suits hardened or finished shafts
• Austenitic stainless steel Grade A2 construction for corrosion resistance
• 3/16-inch internal hex drive for use with standard allen or hex key sets
• Meets ASME/ANSI B18.3 and ASTM F880 standards

Compatibility

Designed as a standard UNC 3/8-16 set screw for use in any mechanical assembly with a conforming threaded bore requiring a flat point, hex-drive fastener per ASME/ANSI B18.3 and ASTM F880 specifications.

Installation Notes

Set screws of this type are typically installed by machinists, millwrights, or qualified maintenance technicians. De-energize and lock out any rotating equipment before installation or removal. Use a correctly sized 3/16-inch hex key to avoid rounding the drive socket. Do not exceed the torque rating appropriate for the thread size and material grade as specified by the applicable fastener standard.
