The VALUE COLLECTION MP40345 is a cup point set screw designed for secure, no-slip fastening in mechanical assemblies where a headless profile is required. Sized at 8-32 UNC thread with a 0.75-inch overall length, this screw is manufactured from Grade 8 alloy steel, delivering high tensile strength and hardness suitable for demanding clamping applications. The cup point geometry bites into the mating surface to resist rotation and axial movement under vibration and load. It is driven with a 5/64-inch hex key and conforms to ASME/ANSI B18.3 and ASTM F912 standards. Sold in a pack of 50 units, this SKU suits shops and field technicians stocking for recurring repair and assembly work.
Cup point set screws in this size range are widely used in HVAC equipment, motors, pulleys, collars, and shaft-to-hub connections found in residential and light commercial mechanical systems. Electricians, HVAC technicians, plumbers, and general maintenance trades reach for this fastener when securing set-screw-style hubs on blower wheels, sheaves, and shaft couplings during equipment service or replacement. The 50-count pack supports both one-off repairs and small-batch assembly operations.
Designed as an OEM-style replacement and general-use fastener for any application requiring an 8-32 UNC cup point set screw with a 0.75-inch overall length.
Set screws are typically installed by licensed mechanics, HVAC technicians, or electricians using a correctly sized hex key to avoid rounding the drive socket. Always de-energize and lock out equipment before servicing any assembly that includes set screws on rotating components. Ensure the mating shaft or bore surface is clean and free of oil before tightening to allow the cup point to seat properly. Do not exceed the rated torque range for 8-32 Grade 8 fasteners as published in applicable ASME standards.
