DIN 912 Socket cap screws, also known as socket head cap screws, allen bolts or socket cap bolts are a type of fastener commonly used in various industrial, mechanical, and construction applications.
These socket cap screws have a cylindrical head with a flat top surface and a recessed hexagonal socket (or "Allen" socket). The socket allows the screw to be tightened or loosened with an Allen wrench or hex key.
We stock hex socket cap screws in different sizes from M1.6 - M12 and in materials including A2 and A4 stainless steel and high tensile steel. They are typically used in applications where precision is critical, such as in aerospace, automotive, and machinery industries.
DIN 912 Allen bolt socket cap screws are a type of fastener commonly used in various applications, including automotive, aerospace, construction, and machinery. They are designed to be used with a socket wrench or allen key, allowing for easy installation and removal. Socket cap screws are known for their clean, low-profile look and their ability to provide a secure and reliable fastening solution. These screws are ideal for use in tight recesses or where space is limited and a spanner can not be used.
We stock socket head cap screws in various materials, including A2 stainless steel, A4 stainless steel, and 12.9 self colour (black) high tensile steel. Each of these materials has its own unique properties and benefits.
A2 stainless steel is a corrosion-resistant material that is commonly used in applications where corrosion resistance is required, such as outdoor environments. A2 stainless steel socket cap screws are also resistant to chemicals and acids, making them ideal for use in harsh environments.
A4 stainless steel is a higher grade of stainless steel than A2. It is ideal for use in marine and coastal environments. A4 stainless steel socket cap screws are also more durable and resistant to wear and tear than A2 stainless steel socket head cap bolts.
12.9 self colour high tensile steel is a type of steel that has been heat-treated to increase its strength and hardness. It is commonly used in applications where high strength and resistance to wear and fatigue are required, such as in the automotive and machinery industries. The self colour finish is achieved by a process of heat treatment and does not provide any corrosion resistance. Therefore, it is not suitable for use in outdoor or corrosive environments.
Overall, the choice of material for socket cap bolts depends on the specific application and requirements. A2 stainless steel and A4 stainless steel are ideal for use in environments where corrosion resistance is required, while 12.9 self colour high tensile steel is best suited for applications where high strength and durability are necessary. The self colour screws will rust so are best suited for indoor use.
