Value Collection 704470PR Set Screw 3/8-16 X 5/8 in Cone Point Ss A2

Product Description

The VALUE COLLECTION 704470PR is a cone point set screw designed for secure, permanent-to-semi-permanent fastening in shaft-to-hub and collar applications. Manufactured from austenitic Grade A2 stainless steel, this fastener resists corrosion in wet, chemical-exposed, and outdoor environments. The 3/8-16 UNC thread and 5/8-inch overall length provide solid engagement in standard tapped holes. Drive is a 3/16-inch internal hex (Allen), conforming to ASME/ANSI B18.3 and ASTM F880 standards. The cone point geometry concentrates clamping force into a small area, biting into the mating shaft surface to resist both axial and rotational movement without requiring a secondary locking feature.

This set screw suits mechanical assemblies requiring corrosion resistance where carbon steel fasteners are not appropriate. Typical applications include HVAC equipment shaft collars, pump impeller hubs, pulley and sprocket retention, and general industrial machinery. Trades including millwrights, HVAC mechanics, and plumbers use this fastener when assembling or servicing rotating components in corrosive or high-humidity service environments. The 3/8-16 UNC thread is among the most common fractional thread sizes in North American mechanical equipment, making this screw a widely applicable service part.

Key Features

• Cone point geometry bites into mating shaft surface for high axial and rotational holding force
• Austenitic Grade A2 stainless steel construction for corrosion resistance in wet and chemical environments
• 3/8-16 UNC thread fits standard tapped holes across a wide range of mechanical equipment
• 3/16-inch internal hex drive compatible with standard Allen key and hex bit sets
• Conforms to ASME/ANSI B18.3 and ASTM F880 dimensional and material standards
• 5/8-inch overall length suits medium-depth collar and hub applications

Compatibility

Designed as a standard 3/8-16 UNC cone point set screw for use in any tapped hole or threaded collar requiring an ASME/ANSI B18.3 compliant internal hex drive fastener in Grade A2 stainless steel.

Installation Notes

Install and remove set screws using a properly sized 3/16-inch hex key or hex bit to avoid rounding the drive socket. Always power down or de-energize rotating equipment and lock out the drive before servicing shaft-mounted components. Engage the cone point carefully against the shaft surface and tighten gradually to avoid deforming soft shaft materials. Refer to equipment manufacturer torque specifications and applicable ASME standards for proper fastener seating in your specific assembly.
