Grade A2 - 70 Hexagon Socket Button Head Cap Screw With Flange Hex Drive ISO 7380
1. Descriptions:
Stainless steel Hexagon Socket Button screws is called stainless steel pan head screws or hex head screws stainless steel cup. Referred to in the general line of stainless steel round cup screws, stainless steel pan head hexagon socket screws as screws and stainless steel countersunk head, that meet the technical requirements of ordinary pan head screws with rust and strong features, generally used in rust and aesthetic requirements high places, such as: household appliances, interior decoration, sanitary installation, elevator decoration. Hex screw production materials SUS201 stainless steel inner pan head, SUS304 stainless steel and SUS316 stainless steel and alloy steel SCM435 or 35crmo. SHCS strength can be achieved within SCM435 alloy steel material production and 35crmo pan head 10.9, it is also known within 10.9 Hexagon pan head screws.Chinese standard for the button head socket cap screw GB/T 70.2-2008. Socket cap screws are a headed and externally threaded part designed for insertion through a close tolerance, internally tapped hole and mated with a nut. Tension on the socket cap screw is induced by rotation of the screw head. There is a hex socket in the head that accepts a hex wrench to tighten the socket cap screw. The point at the threaded end of the socket cap screw is machined flat so it will fit into a drilled hole. Button head socket cap screws have a domed-shaped head that is wider.
Hexagon socket button head cap screws are made of two kinds, both are commonly used materials, stainless steel and carbon steel, carbon steel, we generally refer to iron, carbon steel hardness by grade points, low carbon steel, carbon steel, high carbon steel three. So hex flat head screws of strength class 4.8, 8.8, 10.9, 12.9 of these categories.stainless steel is generally divided into SS304 SS316 A2 A4. Stainless steel has strong corrosion resistance. Mechanical properties of stainless steel screws stronger than steel screws.
