Technical information
Steel ST
- Tensile strength class 5 (500N/mm2)
- visible face fine turned
- black oxide finish
Knurled screws GN 653.2 can easily be made „loss-proof“ for instance in a cover, by the recess cut d4.
To do so, instead of a regular thread / pass through hole, on both sides tapped bores with a thread d1 need to be provided. According to the design of the cover, a clearance bore d5 on one or both sides must be cut additionally.
Depending on the design and required clamping length a1 ... a3 of the cover, there is a choice among the construction variants shown above.
