Value Collection 121085PR Set Screw 10-32 X 1/4 in Cone Point

Product Description

The VALUE COLLECTION 121085PR is a cone point set screw designed for positive locking and point-load engagement in mechanical assemblies. It is manufactured from Grade 8 alloy steel, providing high tensile strength and resistance to shear forces in demanding applications. The screw measures 10-32 thread size with a 1/4 inch overall length and is driven by a 3/32 inch hex key. It conforms to ASME/ANSI B18.3 and ASTM F912 standards, making it a code-compliant fastener for precision industrial and trade use. Machinists, maintenance technicians, and millwrights commonly install this type of fastener in shaft-to-hub connections and setscrew collar assemblies.

The 121085PR cone point set screw is suited for applications where the fastener must bite into or indent a shaft surface to resist rotation or axial movement. Typical use cases include securing pulleys, gears, knobs, and collars to shafts in HVAC blower assemblies, pump drives, and general mechanical equipment. The cone point geometry concentrates clamping force at a single contact point, making it appropriate for permanent or semi-permanent installations where the shaft can accept a small indentation.

Key Features

• Grade 8 alloy steel construction for high tensile and torsional strength
• Cone point tip concentrates holding force for secure shaft engagement
• 10-32 UNF thread for fine-pitch precision fit
• 3/32 inch hex drive compatible with standard hex keys and Allen wrenches
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• 1/4 inch overall length suits shallow boss and thin-collar installations

Compatibility

Designed as a standard UNF 10-32 cone point set screw for use in any mechanical assembly requiring an ASME/ANSI B18.3-compliant fastener with a 3/32 inch hex drive.

Installation Notes

Installation is performed by machinists or maintenance technicians using a calibrated hex key or Allen driver sized at 3/32 inch. Ensure the mating shaft and collar threads are clean and free of debris before driving. Do not exceed the rated torque capacity of the alloy steel fastener by using improvised tools or extensions. Minimum order quantity for this SKU is 100 pieces per order.
