Value Collection 2-SC-25F-100 Set Screw 1/4-28 X 1 in

Product Description

The VALUE COLLECTION 2-SC-25F-100 is a 1/4-28 x 1 inch cup point set screw manufactured from Grade 316 stainless steel with a bright, uncoated finish. Set screws of this type are headless fasteners used to secure a component — such as a collar, pulley, or gear — against a shaft or within a threaded hole. The hex drive allows installation with a standard hex key. Grade 316 stainless steel provides elevated corrosion resistance compared to Grade 304, making this screw suitable for demanding environments including marine, chemical, and high-moisture applications. Licensed trades and maintenance professionals across mechanical, HVAC, and plumbing disciplines commonly use fasteners of this type during equipment assembly and repair.

This set screw is appropriate for light mechanical assemblies requiring a secure, low-profile fastening solution. The cup point geometry bites into the mating surface to resist rotational and axial movement, providing a positive hold without requiring a bolt head clearance. It is well suited for use in tight or recessed locations where a standard cap screw would not fit. Applications span residential and commercial mechanical equipment, pump assemblies, valve actuators, and general industrial machinery maintenance.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in marine and chemical environments
• Cup point geometry grips mating shaft surfaces to resist movement under load
• Hex drive (internal) for installation with a standard hex key or Allen wrench
• Bright, uncoated finish — no coating to crack, flake, or interfere with thread engagement
• 1/4-28 unified fine thread for precise engagement and reduced loosening under vibration
• Headless design allows flush or below-surface installation in confined spaces

Compatibility

Designed as a standard 1/4-28 UNF cup point set screw suitable for any threaded hole or assembly specifying a 1/4-28 headless fastener with cup point geometry.

Installation Notes

Installation requires a correctly sized hex key; use of an ill-fitting key can round the drive socket and strip the fastener. Ensure the mating threaded hole is clean and free of debris before installation. Apply thread-locking compound if vibration resistance beyond the fine thread is required. Always de-energize and lock out any equipment before accessing rotating or pressurized assemblies during fastener installation or removal.
