Value Collection 601093PR Set Screw 4-48 7/16 in Cup Point

Product Description

The VALUE COLLECTION 601093PR is a cup point set screw designed for secure, flush fastening in mechanical assemblies. Manufactured from alloy steel to ASTM F912 and ASME/ANSI B18.3 standards, this screw features a #4-48 UNF thread with an overall length of 7/16 inches. The cup point geometry bites into the mating surface to resist rotation and axial movement without the need for a protruding head. It is driven with a 0.050-inch hex key. Maintenance technicians, machinists, and assemblers working in light mechanical, HVAC component, or electrical equipment applications will find this fastener suitable for precision holding tasks where a headless profile is required.

This set screw is used in applications where a flush or below-surface installation is needed, such as securing collars, pulleys, knobs, or gears to shafts. The fine #4-48 UNF thread provides good holding torque in small-diameter applications. Its compact 7/16-inch length suits tight-clearance assemblies common in motors, fans, and control hardware found in residential and light commercial equipment.

Key Features

• Cup point tip bites into shaft surface for positive rotational and axial hold
• Alloy steel construction meets ASTM F912 material grade requirements
• Conforms to ASME/ANSI B18.3 dimensional standard for hex socket set screws
• #4-48 UNF fine thread for use in small-diameter, close-tolerance assemblies
• Driven with a 0.050-inch hex key — no protruding head profile
• Overall length of 7/16 inches suits tight-clearance component installations

Compatibility

Designed as an OEM-style or maintenance replacement set screw for mechanical assemblies requiring a headless #4-48 UNF cup point fastener conforming to ASME/ANSI B18.3 and ASTM F912 standards.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 0.050-inch hex key. Ensure the mating shaft or bore surface is clean and free of debris before seating the screw. Do not overtighten, as the small thread size is susceptible to stripping or fastener shear at excessive torque. Follow applicable equipment manufacturer torque guidance when specified.
