Threads conform to DIN standard 912 / ISO standard 4762. Requires an internal hexagon key. We offer a wide range of internal hexagon screws in stainless steel A4 (316), available in various thread sizes and lengths. Details can be found in the datasheet and series overview. If A4 stainless steel is not what you are looking for, we also offer internal hexagon head screws made of plain steel, bright zinc-plated steel, titanium, and stainless steel A2 (304) (all according to DIN standard 912). A4 internal hexagon screws with metric threads. The RS Pro internal hexagon screws have a narrow head and are perfect for use in hard-to-reach areas. The fasteners are well-suited for machine repair and maintenance work, as well as in many other fields, including the food and beverage industry, automotive, and aerospace industries. This series of fasteners is made from stainless steel A4 (316), making it ideal for use in the food and beverage industry as well as in offshore and marine applications. Stainless steel A4 (316) has a higher corrosion resistance than stainless steel A2, but is more expensive, yet more cost-effective than titanium, which offers even greater corrosion resistance.

Features and benefits:

• Can be used instead of hexagon screws with less play
• The internal hexagon screw is the strongest of all head designs
• The head height corresponds to the shaft diameter.

Typical applications:

• Machine tool construction and repair
• Safety protection
• Electronic applications
• Household applications
• Medical applications
• Automotive applications
• Plant and maintenance work
• Offshore and shipping applications.
