Value Collection 101127PR Set Screw 5-44 X 1/8 in Cup Point

Product Description

The VALUE COLLECTION 101127PR is a cup point set screw designed for secure, recessed fastening applications in mechanical assemblies. Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength and resistance to loosening under load. The cup point geometry bites into the mating surface to create a firm grip without requiring a through-hole. The hex drive measures 1/16 inch and requires a matching hex key for installation. This fastener meets ASME/ANSI B18.3 and ASTM F912 standards, making it appropriate for precision and general-purpose industrial use. It is sized at 5-44 thread with an overall length of 1/8 inch.

This set screw is used in applications where a headless fastener must bear against or lock into a shaft, collar, or mating component. The 5-44 UNF thread is a fine-pitch designation suited to small-diameter, close-tolerance assemblies common in instrumentation, light mechanical equipment, and precision hardware. Installation is typically performed by machinists, maintenance technicians, or mechanical assemblers working on rotating equipment, motor shafts, or small mechanical linkages requiring positive locking of components.

Key Features

• Cup point geometry provides a biting grip on mating shaft or surface
• Grade 8 alloy steel construction for high tensile and proof load strength
• 5-44 UNF fine-pitch thread for close-tolerance small-diameter applications
• 1/16 inch hex drive accepts standard hex key tools
• Meets ASME/ANSI B18.3 and ASTM F912 fastener standards
• Headless profile sits flush or below surface when fully driven

Compatibility

Designed as a standard-dimension replacement or supplemental set screw for any assembly specifying a 5-44 UNF cup point set screw with a 1/8 inch overall length and 1/16 inch hex drive per ASME/ANSI B18.3.

Installation Notes

This fastener is installed by mechanical technicians or machinists using a 1/16 inch hex key. Ensure the mating component is fully de-energized and stationary before installation or removal. Do not over-torque; the small drive size is susceptible to key or socket rounding if excessive force is applied. Confirm thread engagement depth is sufficient to achieve the required holding force before putting the assembly back into service.
