Value Collection NT-440-375-SS Set Screw 4-40 3/8in Ss 18-8

Product Description

The VALUE COLLECTION NT-440-375-SS is a 4-40 UNC hex-drive set screw with a nylon soft tip point, manufactured from grade 18-8 stainless steel. At 3/8 inches in thread length, this fastener is designed to secure components without marring or damaging the mating surface, making it the preferred choice when locking shafts, collars, or knobs where surface finish must be preserved. The nylon tip compresses on tightening to grip firmly while protecting soft materials. Stainless steel construction provides corrosion resistance suitable for demanding environments. This part is sold in a minimum order quantity of 10 pieces.

This set screw is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical panel and control component mounting, plumbing fixture hardware, and general mechanical assembly. The 4-40 thread size is common in small-diameter shaft collars, knobs, and precision instrument housings. The soft nylon tip makes it especially well suited for use on polished shafts, plastic components, or any application where a hardened cup or cone point would cause damage. Installers in HVAC, electrical, and light mechanical trades will encounter this fastener in both OEM and field-repair contexts.

Key Features

• Nylon soft tip protects mating surfaces from marring or gouging during tightening
• Grade 18-8 stainless steel construction resists corrosion in moisture-exposed environments
• 4-40 UNC thread standard ensures broad compatibility with standard tapped holes
• Hex drive accepts standard hex keys for precise torque application in tight spaces
• 3/8-inch thread length suits shallow-to-medium engagement depth requirements
• Minimum order quantity of 10 supports both single-job and stock replenishment needs

Compatibility

Designed as a standard 4-40 UNC hex socket set screw with soft nylon tip, suitable for use in any application requiring a 4-40 tapped hole and a non-marring point type.

Installation Notes

Installation is performed with a properly sized hex key or Allen driver matched to the socket drive. Ensure the tapped hole is clean and free of debris before threading the screw. Do not overtighten, as excessive torque may deform or extrude the nylon tip, reducing its holding and protective function. Follow applicable equipment manufacturer torque guidelines and NEC or IFGC code requirements as relevant to the assembly being serviced.
