Overview

 

Metric DIN 7991 hexagon socket cap screws have a flat countersunk head with an internal hexagonal drive suited for a hex / Allen key or wrench. The internal drive is ideal for situations where externally wrenched screws are impractical such as in applications where limited space is available. Furthermore, the flat countersunk head allows for the head to lie flush with the surface of the substrate. Jinpeng Fasteners offers an extensive range of metric DIN 7991 hexagon socket cap screws as well other inch and metric industrial fasteners for immediate delivery from stock. The following sizes of metric DIN 7991 hexagon socket cap screwsare available for immediate shipping from stock: Diameters ranging from M3to M24in lengths up to 150mm, in steel and stainless steel A2 and A4.
