Value Collection 131154PR Set Screw 5/16-18 X 3/4 in Oval Point

Product Description

The VALUE COLLECTION 131154PR is a Grade 8 alloy steel set screw with an oval point, designed for secure fastening applications where a hardened, headless fastener is required. Threaded 5/16-18 UNC and measuring 3/4 inches in overall length, this screw is driven with a 5/32-inch hex key. Grade 8 alloy steel construction provides high tensile strength and resistance to shear forces, making it suitable for demanding mechanical assemblies. It conforms to ASME/ANSI B18.3 and ASTM F912 standards. Installation and quality control professionals will find this part meets consistent dimensional and hardness requirements for production and maintenance use.

This set screw is used in mechanical assemblies across industrial, HVAC, plumbing, and electrical applications where a flush or recessed fastener is needed to secure components such as pulleys, collars, or couplings to shafts. The oval point provides a moderate bearing surface that resists loosening under vibration while minimizing damage to the mating shaft surface. Suitable for use in both original equipment manufacturing and field-repair contexts where a UNC-threaded, headless fastener of this size is specified.

Key Features

• Grade 8 alloy steel construction for high tensile and shear strength
• Oval point design minimizes shaft marring while maintaining firm seating
• 5/16-18 UNC thread for compatibility with standard tapped holes
• 3/4-inch overall length suits medium-depth fastening applications
• 5/32-inch hex drive for use with standard hex keys or Allen wrenches
• Conforms to ASME/ANSI B18.3 and ASTM F912 dimensional and material standards

Compatibility

Designed as an OEM-style and replacement-use set screw for any assembly specifying a 5/16-18 UNC x 3/4-inch overall length oval-point fastener per ASME/ANSI B18.3 and ASTM F912.

Installation Notes

Set screws of this type are typically installed by mechanical technicians, HVAC service professionals, or maintenance personnel using a calibrated hex key of the correct size. Always ensure the mating tapped hole is clean and free of debris before installation. Do not over-torque, as Grade 8 set screws in alloy housings can strip threads if driven beyond specification. Follow applicable mechanical assembly codes and the equipment manufacturer's torque guidance where provided.
