Product Introduction

Allen bolts, also known as DIN912 hexagon socket head cap bolts, are a popular choice for mechanical installations. These bolts offer a reliable and secure fastening solution, thanks to their unique design that makes them easy to assemble and disassemble. The hexagon socket head ensures that there is no slipping or stripping during installation or removal, providing dependable performance with every use. Given their versatility and reliability, it comes as no surprise that hexagon socket head bolts are widely used across a range of mechanical applications.

The hex socket bolt, also known as a DIN912 bolt, is a metric product that comes in various thread diameters ranging from M1.4 to M64. These bolts are often made of carbon steel, with grades 8.8, 10.9, and 12.9 being the most common. The thread tolerance for these bolts is generally 6g, although grade 12.9 bolts have a tighter tolerance of 5g 6g.
Aside from carbon steel, hex socket bolts can also be made from other materials such as stainless steel, copper, and nylon 6.6. The grade of stainless steel commonly used is A2-70, A4-70, and A4-80. The surface treatment of hex socket bolts varies, but black and galvanized finishes are common.
In summary, DIN912 hex socket bolts come in various sizes and grades, with carbon steel being the most common material used. These bolts can also be made from stainless steel, copper, and nylon 6.6 and are often finished with black or galvanized coatings.
