DIN 7500-1, hexagon head with collar, case-hardened (-O-) galvanised steel, blue passivated (A2K)

Thread-rolling screws form a nut thread in cast blind holes, rim holes and drilled, lasered and punched sheet metal parts. Unlike thread cutting, thread rolling does not interrupt the material structure in the counter thread. Instead, the material is displaced and strain-hardened.

Eliminates thread cutting

Cost savings

Chip-free thread formation

TRILOBULAR shape of the screw combined with the radius profile of the thread flanks

Low rolling torques with large thread flank overlap

High clamping force

Large thread flank overlap

High load capacity

Strain-hardened counter thread (nut thread)

Greater load capacity

Play-free and self-locking thread seating

Reduced likelihood of screw working loose

Protection against loss

The formed thread corresponds to a standard metric thread

Notice

The values for the hole diameters are guideline values, which should be verified by testing the original parts. Further information can be found in the DIN 7500-2 standard.
