Value Collection 101013PR Set Screw 0-80 X 3/16 in Cup Point

Product Description

The VALUE COLLECTION 101013PR is a cup point set screw designed for precise, low-profile fastening in mechanical assemblies. Manufactured from Grade 8 alloy steel, this screw delivers high tensile strength and resistance to loosening under vibration and load. The cup point geometry bites into the mating surface to create a secure, positive hold without requiring a through-hole. At a thread size of 0-80 UNF and an overall length of 3/16 inches, this fastener targets fine-pitch applications where space is constrained and holding force must be reliable. Installation is performed with a 0.028-inch hex key. It conforms to ASME/ANSI B18.3 and ASTM F912 standards.

This set screw is used in precision mechanical and light industrial applications where a headless fastener is required to secure a component to a shaft, collar, or housing. Typical uses include instrument assemblies, optical mounts, small motor shafts, and precision machine components. The fine 0-80 UNF thread pitch is well suited to thin-walled or closely toleranced parts where coarse threads would strip or not engage properly. Licensed mechanics, machinists, and maintenance technicians working with fine-pitch fastener applications are the primary installers.

Key Features

• Cup point design bites into the mating surface for a secure, vibration-resistant hold
• Grade 8 alloy steel construction provides high tensile and torsional strength
• 0-80 UNF fine thread pitch for use in thin-walled or precision-toleranced assemblies
• Headless hex drive profile keeps the fastener flush or below the surface
• Conforms to ASME/ANSI B18.3 and ASTM F912 fastener standards
• 0.028-inch hex key drive minimizes the required installation footprint

Compatibility

Designed as an OEM-style replacement or direct-use set screw for precision mechanical assemblies requiring a 0-80 UNF thread, cup point, Grade 8 alloy steel fastener in compliance with ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Install using a calibrated 0.028-inch hex key to avoid rounding the drive socket. Ensure the mating shaft or housing is clean and free of debris before seating the cup point. Do not exceed the rated torsional capacity of the 0-80 thread by over-torquing. This fastener is intended for installation by machinists or qualified mechanical technicians familiar with fine-pitch fastener procedures.
