Fastenic Group India Is leading manufacturer of Stainless Steel DIN 7991 Allen CSK Machine Screw in 304 & 316 Grade. DIN 7991 is a standard specification for Allen CSK machine screws. Here are the key characteristics of DIN 7991 Allen CSK Machine Screw machine screws:

• Head Style: Flat Countersunk Head – The head of the screw is flat on top with an angled countersunk profile. This design allows the screw to sit flush with the surface when fully tightened.

• Drive Type: Typically, DIN 7991 screws have socket or hex socket drives. Socket drive screws require an Allen key (hex key) or a similar tool for installation.

• Thread Type: Metric – DIN standards use metric threads. The thread size and pitch will be specified according to the DIN 7991 standard.

• Material: DIN 7991 screws can be made from various materials, including steel, stainless steel, brass, aluminum, and others. The choice of material depends on factors like the application’s requirements and environmental conditions.

DIN 7991 flat countersunk head screws are commonly used in applications where a flush or low-profile appearance is required. The angled countersunk head allows the screw to sit level with the surface it’s fastened to, reducing the risk of snagging or obstruction. These screws are widely used in industries such as construction, furniture assembly, automotive, and machinery. When sourcing or using DIN 7991 screws, it’s essential to refer to the specific DIN standard or the manufacturer’s documentation to obtain the exact specifications for the screws you require for your application.
