Value Collection 131109PR Set Screw 1/4-20 X 1/2 in Oval Point

Product Description

The VALUE COLLECTION 131109PR is a 1/4-20 x 1/2 inch alloy steel set screw with an oval point, designed for secure fastening applications where a flush or recessed fastener is required. Manufactured to Grade 8 alloy steel, this set screw delivers high tensile strength and resistance to shear forces. The 1/8 inch hex drive accepts a standard hex key for installation and torquing. Conforming to ASME/ANSI B18.3 and ASTM F912 standards, this fastener is appropriate for industrial, mechanical, and trade assembly work where dimensional and material compliance is required.

This set screw is used in mechanical assemblies where a shaft, collar, or component must be locked to a mating part without a protruding head. The oval point style provides a centered, low-damage contact against the mating shaft, making it suitable for applications where the shaft surface must not be severely marred. Typical applications include motor shafts, pulleys, collars, and similar rotating or fixed mechanical components in light industrial and commercial equipment. Minimum order quantity is 100 pieces, sold in single-piece package increments.

Key Features

• 1/4-20 UNC thread size for broad compatibility with standard tapped holes
• Oval point contact reduces shaft damage compared to cup or cone point styles
• Grade 8 alloy steel construction provides high tensile and proof load strength
• 1/8 inch hex drive accepts common hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Overall length measured at 1/2 inch for compact, low-profile installations

Compatibility

Designed as a standard 1/4-20 UNC set screw for use in any application requiring a Grade 8 alloy steel oval point fastener conforming to ASME/ANSI B18.3 and ASTM F912 specifications.

Installation Notes

Installation is performed with a 1/8 inch hex key. Ensure the mating component is clean and properly aligned before seating the screw. Power down or de-energize any associated equipment before servicing mechanical assemblies containing set screws. Do not exceed the rated drive torque for the fastener size, and confirm the tapped hole thread condition prior to installation to prevent cross-threading or galling.
