Value Collection 101477P Set Screw 3/8-24 X 3/8 in Cup Point Grade 8

Product Description

The VALUE COLLECTION 101477P is a cup point set screw designed for secure, vibration-resistant fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this fastener delivers high tensile strength and hardness suitable for demanding industrial and trade applications. The 3/8-24 thread size indicates a fine-thread (UNF) pitch, providing precise clamping force control. The 3/16-inch hex drive accepts a standard hex key for installation and removal. Overall length is 3/8 inches. This screw conforms to ASME/ANSI B18.3 and ASTM F912 standards, ensuring dimensional consistency and material compliance. Electricians, millwrights, HVAC technicians, and general maintenance trades use cup point set screws in collar, pulley, sprocket, and shaft-locking applications.

The 101477P is suited for use in shaft-to-hub connections, set collar locking, and similar mechanical fastening scenarios where a headless fastener is required to sit flush or below the surface of the workpiece. The cup point geometry bites into the shaft surface to resist rotational and axial movement. This fine-thread variant is well matched to applications requiring precise torque control or use in harder base materials.

Key Features

• Grade 8 alloy steel construction for high tensile and proof load strength
• Cup point geometry provides positive bite into shaft surfaces to resist movement
• 3/8-24 fine thread (UNF) for precise clamping force and use in harder materials
• 3/16-inch hex drive compatible with standard hex keys and Allen wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design allows the fastener to sit flush or recessed in the tapped hole

Compatibility

Designed as a standard headless cup point set screw for use in any application with a tapped 3/8-24 (UNF) thread hole requiring a 3/16-inch hex drive fastener of 3/8-inch overall length.

Installation Notes

Installation and removal require a 3/16-inch hex key. Ensure the mating tapped hole is clean and free of debris before threading the fastener. Degrease shaft and bore contact surfaces if a permanent or high-torque lock is required. Always confirm thread engagement depth is adequate for the load before applying final torque.
