Value Collection 111148PR Set Screw 8-32 X 3/8 in Grade 8

Product Description

The VALUE COLLECTION 111148PR is a Grade 8 alloy steel set screw with an 8-32 UNC thread and an overall length of 3/8 inches. It features a knurled cup point for positive grip and a 5/64-inch hex drive for socket key installation. Manufactured to ASME/ANSI B18.3 and ASTM F912 standards, this fastener is suited for mechanical assemblies where a headless, flush-mount clamping solution is required. The knurled cup point bites into mating surfaces to resist loosening under vibration, making it appropriate for shaft-to-hub locking, collar positioning, and similar light mechanical holding applications. Licensed trades and maintenance professionals routinely stock this size for equipment repair and fabrication work.

This set screw is used in residential, commercial, and industrial mechanical assemblies wherever a compact, internal-drive fastener is needed to secure a component to a shaft or within a threaded bore. Typical applications include motor shaft collars, gear hubs, pulleys, and adjustment mechanisms. The 8-32 UNC thread is one of the most common fine-coarse fastener sizes in light-duty mechanical and HVAC equipment assemblies. Minimum order quantity is 100 pieces; package quantity is 1.

Key Features

• Knurled cup point provides positive grip and resists rotation under vibration
• Grade 8 alloy steel construction for high tensile strength in compact fastener form
• 5/64-inch hex drive accepts standard hex key or Allen wrench
• 8-32 UNC thread is widely compatible with standard tapped holes in light mechanical equipment
• Meets ASME/ANSI B18.3 and ASTM F912 dimensional and material standards
• Headless design sits flush or below surface for unobstructed assembly clearance

Compatibility

Designed as an OEM-style or aftermarket replacement set screw for any assembly requiring an 8-32 UNC threaded, headless cup-point fastener with a 5/64-inch hex drive.

Installation Notes

Installation is performed with a 5/64-inch hex key or Allen wrench; use a calibrated torque driver where joint specifications require it. Ensure the mating threaded bore is clean and free of debris before driving. Do not exceed the torque rating of the assembly or the mating component material. A licensed mechanic, millwright, or maintenance technician should confirm proper seating and holding force before returning equipment to service.
