Value Collection 409200PR Cup Point Set Screw 9/16-12

Product Description

The VALUE COLLECTION 409200PR is a cup point set screw designed for mechanical fastening applications where a headless, flush-seated fastener is required. Manufactured from alloy steel to Grade 2 material standards, this set screw measures 9/16-12 thread size with a 1-inch length measured under the head. The square drive provides positive torque engagement, reducing slip during installation. It is used to secure rotating components such as collars, pulleys, gears, and hubs to shafts. Maintenance technicians and mechanical contractors working on HVAC equipment, motors, and general mechanical assemblies will find this fastener a straightforward stock item.

This set screw is suited for residential and light commercial mechanical applications where UNC thread fasteners are specified. The cup point geometry creates an indentation on the mating shaft surface, producing a secure hold against axial and rotational movement. It is commonly installed in shaft collars, shaft couplings, and set screw hubs as part of routine equipment assembly or field repair work. Minimum order quantity is 10 pieces, sold in individual package quantity of 1.

Key Features

• Cup point geometry bites into shaft surface for reliable axial and rotational hold
• Square drive socket for positive torque engagement during installation
• Alloy steel construction, Grade 2 material standard
• 9/16-12 UNC thread for compatibility with standard fractional inch tapped holes
• 1-inch length measured under head for accurate depth placement
• Headless design allows flush or sub-flush seating in most applications

Compatibility

Designed as a standard UNC fractional inch set screw for use in shaft collars, pulleys, gears, and mechanical hubs requiring a 9/16-12 tapped hole.

Installation Notes

Installation is performed by qualified mechanical technicians or maintenance personnel. Always power down and de-energize rotating equipment before installing or removing set screws. Use a calibrated square drive key of the correct size to avoid rounding the drive socket. Follow applicable equipment manufacturer torque guidelines and relevant mechanical codes when specifying fastener engagement depth.
