Value Collection 603425BR Set Screw 5/8-11 X 1 in Flat Point Grade 8

Product Description

The VALUE COLLECTION 603425BR is a 5/8-11 UNC flat point set screw manufactured from Grade 8 alloy steel. Measuring 1 inch in overall length, this headless fastener is driven with a 5/16-inch hex key and seats flush against a shaft or surface without protruding. Grade 8 alloy steel delivers the high tensile strength and hardness required for demanding clamping and locking applications. The flat point distributes clamping force over a broad contact area, making it well suited for use against hardened shafts or finished surfaces where a cupped or cone point would cause marking or distortion. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is used in mechanical assemblies where a collar, gear, pulley, or similar component must be locked onto a shaft. Flat point geometry is preferred when the mating surface is hardened or polished, or when repeated adjustment is anticipated. Typical applications include industrial machinery, power transmission assemblies, and general mechanical maintenance. Installers in manufacturing, millwright, and maintenance trades reach for this fastener when torque transmission and surface protection are both priorities. Sold individually with a minimum order quantity of 10 pieces.

Key Features

• Grade 8 alloy steel construction for high tensile strength and hardness
• Flat point design protects mating shaft surfaces from deformation
• 5/16-inch hex drive for standard hex key installation
• 5/8-11 UNC thread for broad compatibility with standard tapped holes
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 1 inch overall length suits medium-depth engagement applications

Compatibility

Designed as a standard UNC set screw for use in any tapped 5/8-11 hole requiring a flat point, headless fastener per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed with a 5/16-inch hex key torqued to the value specified by the equipment manufacturer for the thread size and grade. Ensure the tapped hole is clean and free of debris before driving the screw. Do not exceed the rated torque for Grade 8 fasteners, as over-torquing can damage threads in softer mating materials. De-energize and lock out any rotating equipment before servicing fasteners on shafts or rotating assemblies.
