Value Collection BT3816-500-AS25 Set Screw 3/8-16 X 1/2 in Grade 8

Product Description

The VALUE COLLECTION BT3816-500-AS25 is a Grade 8 alloy steel set screw with a 3/8-16 UNC thread and a 1/2-inch thread length. It features a hex drive socket and a soft tip point with a brass tip insert, which reduces marring on the mating shaft or surface while still holding position under load. Set screws of this type are standard hardware in mechanical assemblies where a fastener must seat flush or below the surface of the host component. This package contains 25 pieces, making it suitable for small-batch production work, service kits, or shop stock replenishment.

This set screw is used in rotating equipment, motor shaft collars, couplings, pulleys, and similar mechanical assemblies found in HVAC equipment, pumps, fans, and general industrial machinery. The soft brass tip is appropriate wherever the mating shaft or component surface must be protected from the hardened steel point. The 3/8-16 UNC thread is a common coarse-thread standard seen across a wide range of manufactured equipment in residential, commercial, and light industrial applications. Installation requires a hex key or allen wrench of the appropriate drive size.

Key Features

• Soft tip point with brass insert protects mating shaft surfaces from damage during tightening
• Grade 8 alloy steel construction provides high tensile and proof load strength
• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• Hex drive socket allows installation with a standard allen key or hex bit driver
• 1/2-inch thread length suits shallow-bore collars and thin-wall hubs
• 25-piece pack supports shop stock, service kits, or small-batch assembly work

Compatibility

Designed as a standard UNC coarse-thread set screw for use in any application requiring a 3/8-16 tapped hole with a soft-tip or cup-point fastener.

Installation Notes

Set screws of this type are typically installed by mechanical technicians and millwrights using a hex key or T-handle driver of the correct drive size. Before installation, de-energize and lock out any rotating equipment per applicable OSHA lockout/tagout procedures. Do not overtighten beyond the rated torque range for Grade 8 hardware, and confirm the brass tip is seated properly before applying final torque. Inspect the mating shaft for burrs or contamination that could affect clamping performance.
