Value Collection BT-3816-625-AS Set Screw 3/8-16 X 5/8 in

Product Description

The VALUE COLLECTION BT-3816-625-AS is a Grade 8 alloy steel set screw with a 3/8-16 UNC thread and a 5/8-inch threaded length. It features a hex drive socket and a soft tip point with a brass insert, which protects mating shaft surfaces from damage during and after installation. This fastener is used in mechanical assemblies where a hardened screw must hold a component in position on a shaft without marring the shaft surface. The Grade 8 alloy steel body provides high clamp load and resistance to loosening under vibration, while the softer brass tip prevents galling on the shaft.

This set screw is suited for industrial, HVAC, and general mechanical maintenance applications where shaft-mounted components such as collars, pulleys, couplings, sheaves, and hubs require secure positioning. The soft brass tip makes it appropriate for use on finished or hardened shafts where a hardened cup point would cause unacceptable surface damage. Technicians in HVAC, plumbing, and mechanical trades commonly use this style of fastener when servicing blower wheel assemblies, motor shaft components, and similar rotating equipment.

Key Features

• Grade 8 alloy steel body delivers high tensile strength and vibration resistance
• Soft brass tip protects shaft surfaces from galling and indentation
• Hex drive socket accepts standard hex keys for precise torque application in tight spaces
• 3/8-16 UNC thread is a widely stocked, industry-standard size for mechanical assemblies
• Full-thread construction with length measured as threaded length at 5/8 inches

Compatibility

Designed as a standard 3/8-16 UNC soft tip set screw suitable for use in any mechanical assembly requiring that thread size and a non-marring point style. Verify thread pitch and drive size against the existing fastener before installation.

Installation Notes

Installation is typically performed by a mechanic, HVAC technician, or plumber using a properly sized hex key or hex bit driver. Always de-energize and lock out equipment before accessing shaft-mounted components. Do not substitute a standard cup point set screw for this soft tip version in applications where shaft surface protection is required. Confirm thread engagement depth is adequate before applying final torque.
