Value Collection MP40362 Set Screw 1/4-20 X 3/8 in Grade 8 50pk

Product Description

The VALUE COLLECTION MP40362 is a cup point set screw designed for secure, flush fastening in mechanical assemblies where a protruding head is not practical. Threaded 1/4-20 UNC with an overall length of 3/8 inches, this fastener is driven by a 1/8-inch hex key and seats via a cup point that bites into the mating surface to resist rotation and axial movement. Manufactured from Grade 8 alloy steel, it meets ASME/ANSI B18.3 and ASTM F912 standards. Sold in a pack of 50, this SKU suits shops and field technicians who need reliable stock on hand for repeated service calls or production runs.

Cup point set screws like the MP40362 are commonly used in shaft-collar and hub-to-shaft applications across HVAC blower assemblies, pump drives, motor mounts, and general mechanical systems. The cup point geometry is preferred when a semi-permanent grip on a shaft is needed without a through-hole or external fastener. This fastener is appropriate for both light industrial production and maintenance repair operations requiring a compact, headless fastening solution.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 3/8-inch overall length suits shallow engagement applications
• Cup point geometry bites into mating shaft surface to resist loosening under vibration
• Grade 8 alloy steel construction provides high tensile and proof load strength
• Driven by 1/8-inch hex key — no special tooling required
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Pack of 50 supports high-frequency service or production use

Compatibility

Designed as a standard 1/4-20 UNC cup point set screw conforming to ASME/ANSI B18.3, suitable for any tapped 1/4-20 set screw application that accepts a headless hex-drive fastener.

Installation Notes

Set screws should be installed by a qualified mechanic or technician using a properly sized 1/8-inch hex key to avoid rounding the drive socket. De-energize or lock out the equipment before disassembling any shaft-collar or hub assembly. Apply thread-locking compound only if specified by the equipment manufacturer, as over-application can make future disassembly difficult. Torque to the equipment manufacturer's specification for 1/4-20 Grade 8 set screws.
