Hexagon Socket Button Head Screws
Hexagon Socket Button Head Screws have a rounded, low-profile head with an internal hexagon socket, providing a neat appearance and convenient installation where space around the fastener is limited. The button head offers a larger bearing surface than a countersunk head while keeping the overall head profile relatively low, making these screws suitable for machinery, equipment, fixtures, and general assembly applications.
We manufacture Hexagon Socket Button Head Screws in metric and inch sizes according to the required dimensions and specifications. Our production includes multi-station cold heading and thread rolling, with additional machining and inspection available for customized dimensions, materials, and surface finishes. Each batch is checked for critical dimensions, thread quality, and mechanical requirements before shipment.

Mechanical Property:
Carbon and Alloy Steel — ISO 898-1
Metric Hexagon Socket Button Head Screws in carbon and alloy steel can be supplied according to ISO 898-1. Common property classes include 8.8, 10.9, and 12.9. The applicable requirements cover tensile strength, yield strength, proof load, and hardness according to the specified property class and screw size.
Stainless Steel — ISO 3506-1
Metric stainless steel Hexagon Socket Button Head Screws can be supplied according to ISO 3506-1. Common stainless steel groups include A2 and A4, with strength classes such as 50, 70, and 80. Mechanical requirements include tensile strength, 0.2% proof stress, elongation, and hardness, depending on the specified material and strength class.
Alloy Steel — ASTM F835
For inch-size alloy steel Hexagon Socket Button Head Screws, ASTM F835 specifies the applicable mechanical requirements. The screws are manufactured from alloy steel and heat treated to achieve the required strength and hardness. Tensile strength and hardness are controlled according to the requirements of the specification.
Stainless Steel — ASTM F879
For inch-size stainless steel Hexagon Socket Button Head Screws, ASTM F879 specifies the applicable material and mechanical requirements. Different stainless steel grades and strength conditions can be supplied according to the specified alloy and application. Tensile strength, yield or proof requirements, hardness, and other applicable properties are verified during production and inspection.
