ASME B18.3 Oval Point Socket Set Screws
ASME B18.3 oval point socket set screws feature a rounded, oval-shaped tip and an internal hex drive for installation in threaded holes. The oval point provides a rounded contact surface that helps reduce damage to the mating surface compared with sharper-pointed designs. These screws are suitable for positioning, adjustment, and securing components where controlled contact is required.
We supply ASME B18.3 oval point socket set screws in alloy steel and other available materials, with options for different sizes, lengths, and finishes. The available size range is 0#-2″. Our manufacturing capabilities include cold heading, thread rolling, and precision inspection to help ensure consistent dimensions and product quality.

Mechanical Property:
ASTM F912 — Alloy Steel Oval Point Socket Set Screws
Alloy steel oval point socket set screws are suitable for mechanical assemblies where a rounded contact tip is required to secure or position components. For these screws, ASTM F912 specifies the requirements for quenched and tempered alloy steel, including a hardness range of 45–53 HRC and requirements for torsional strength and material quality. These properties help determine whether the selected screws meet the mechanical requirements of the intended assembly.
ASTM F880 — Stainless Steel Oval Point Socket Set Screws
Stainless steel oval point socket set screws are an option for assemblies that require corrosion resistance alongside reliable positioning. ASTM F880 covers austenitic stainless steel socket set screws, with requirements for material composition, torque performance, hardness, and corrosion resistance. The appropriate stainless steel grade and material condition should be selected according to the operating environment and the requirements of the finished assembly.
