Value Collection R40342462 Set Screw 2-56 Cup Point Ss 18-8

Product Description

The VALUE COLLECTION R40342462 is a 2-56 UNC cup point set screw machined from grade 18-8 stainless steel. It measures 3/32 inches in overall length and is driven with a hex key sized at 0.035 inches. The cup point tip bites into the mating shaft surface to resist rotation and axial movement without requiring a protruding head. This type of fastener is commonly installed by machinists, maintenance technicians, and assembly mechanics in light mechanical assemblies where a flush or recessed fastener is required.

Cup point set screws in the 2-56 thread size are used in precision instrument assemblies, small motor shafts, knobs, collars, and mechanical linkages where space constraints make headed fasteners impractical. The 18-8 stainless steel construction offers corrosion resistance suitable for light industrial, marine-adjacent, and general mechanical applications. This part is sold individually but carries a minimum order quantity of 100 pieces.

Key Features

• 2-56 UNC thread for compatibility with fine-pitch light-duty assemblies
• Cup point geometry bites into shaft surface for positive retention
• Grade 18-8 stainless steel construction resists corrosion
• Hex socket drive accepts a 0.035-inch hex key
• 3/32-inch overall length suits compact, space-restricted installations

Compatibility

Designed as a standard 2-56 UNC cup point set screw for use in collars, shaft couplings, knobs, and small mechanical assemblies requiring a headless threaded fastener in this thread size.

Installation Notes

Installation requires a properly sized 0.035-inch hex key to avoid rounding the drive socket. Ensure the mating shaft or component is clean and free of debris before seating the screw. Do not exceed the torque capacity appropriate for the 2-56 thread size in stainless steel, as the small cross-section is susceptible to galling and thread stripping. Anti-galling compound is commonly used with stainless steel fasteners to reduce friction during installation.
