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
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
