Countersunk Torx screw A2 - our own illustration of the family

Screws M4x10 Torx T20 A2 with flat countersunk head

Screws with a Torx T20 hexalobular drive and a flat 90° countersunk head. Material: stainless steel A2. The right-hand metric M4 thread has a pitch of 0,7 mm. Installation requires the correct Torx bit and a properly formed countersink.

Dimensions and design

Overall length L is 10 mm and includes the head. Head diameter dk is 8 mm and head height k is max. 2,3 mm. ISO 10642 and DIN 7991 are approximate catalogue references, without a declaration of strict conformity to the standards.

Due to the non-standard head geometry, the product has limited load capacity. No confirmed strength class or threaded length is given for this variant. Selection for the required load must take this characteristic into account.
