Value Collection 101333PR Set Screw 1/4-20 X 2 in Cup Point

Product Description

The VALUE COLLECTION 101333PR is a Grade 8 alloy steel cup point set screw sized 1/4-20 x 2 inches. Set screws are fully threaded, headless fasteners used to secure a component — such as a gear, pulley, or collar — against a shaft by biting into or pressing against the mating surface. The cup point geometry concentrates clamping force at the contact zone, providing strong resistance to rotation and axial movement. The 1/8-inch internal hex drive accepts a standard hex key for installation in confined spaces. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards and is suitable for mechanical assembly applications where a flush or recessed fastener is required.

This set screw is commonly used in light industrial and mechanical maintenance applications including motor shaft collars, set collar assemblies, conveyor components, and general machine assembly where a 1/4-20 UNC thread is specified. The 2-inch overall length accommodates deeper engagement requirements. Installation is performed by maintenance technicians and mechanical assemblers using a 1/8-inch hex key. Sold individually per package with a minimum order quantity of 100 pieces.

Key Features

• Cup point geometry bites into shaft surface for firm, vibration-resistant hold
• Grade 8 alloy steel construction provides high tensile and proof load strength
• 1/4-20 UNC thread standard for broad tooling and hardware compatibility
• 1/8-inch hex drive allows installation with a standard hex key in tight clearances
• Fully threaded, headless design seats flush or below the host material surface
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and performance standards

Compatibility

Designed as a standard 1/4-20 UNC cup point set screw for use in any mechanical assembly or shaft-locking application requiring a Grade 8 alloy steel fastener at 2-inch overall length.

Installation Notes

Installation requires a 1/8-inch hex key and should be performed with the assembly de-energized and at rest. Ensure the mating shaft and threaded bore are clean and free of debris before seating the screw. Apply appropriate thread-locking compound if vibration is a concern in the application. Follow applicable ASME or machine-builder torque guidelines for 1/4-20 Grade 8 set screws.
