Value Collection 704429PR Set Screw 5/16-18 X 1/2 in Cone Point

Product Description

The VALUE COLLECTION 704429PR is a cone point set screw designed for secure, positive locking in mechanical assemblies where the point must bite into or indent the mating surface. Manufactured from austenitic stainless steel Grade A2, it offers good corrosion resistance suited to general industrial, HVAC, and plumbing applications. The 5/16-18 UNC thread and 1/2-inch overall length make it a standard fastener for shaft collars, pulleys, and adjustment mechanisms. Drive is a 5/32-inch internal hex (Allen) socket. Licensed trades and mechanical contractors install this type of fastener during equipment assembly, motor mounting, and component adjustment work.

This set screw is appropriate for residential and light commercial mechanical systems where a non-galling, corrosion-resistant fastener is required. Typical applications include securing rotating components to shafts, locking adjustment points on valve stems, and fastening collars in HVAC blower assemblies. The cone point geometry concentrates clamping force at a single contact point, making it effective for permanent or semi-permanent installations on hardened or unhardened shaft surfaces. Sold individually; minimum order quantity is 10 pieces per order.

Key Features

• Cone point geometry provides positive engagement and high holding force on shaft surfaces
• Austenitic Grade A2 stainless steel construction for corrosion resistance in wet or humid environments
• 5/16-18 UNC thread standard ensures broad compatibility with standard tapped holes
• 5/32-inch hex drive accepts standard Allen keys and hex bit drivers
• Meets ASME/ANSI B18.3 and ASTM F880 fastener standards
• Fractional inch sizing for straightforward specification and replacement

Compatibility

Designed as a standard UNC set screw for use in any 5/16-18 tapped hole requiring a cone point fastener; suitable for shaft collars, pulleys, couplings, and similar mechanical components across HVAC, plumbing, and general industrial equipment.

Installation Notes

Installation is performed with a 5/32-inch hex key or Allen-drive bit. Always de-energize and lock out equipment before accessing rotating assemblies or drive components. Tighten to the assembly specification using a calibrated hex key torque handle where precise clamping is required. Cone point set screws create an indent in the mating surface; verify the shaft or component material is compatible before installation to prevent damage.
