HUS4 Bonded screw

Product Technical Datasheet

Steel-to-concrete
Update: March 25
HUS4 Bonded screw anchor for use in concrete
Ultimate performance screw anchor for single point fastening
Anchor version Benefits
- High productivity - less drilling and fewer
HUS4-H(F) operations than with conventional
(10-16) anchors
- ETA approval for cracked and uncracked
HUS4-C concrete
(10)
- ETA approval for Seismic C1 and C2
HUS4-A(F) - ETA approval for adjustability1)
(10 and 14) (unscrew-rescrew)
- Smaller edge and spacing distance
- One embedment at the level of h.nom3
HUS4-HR of HUS4 for maximum performance
(10 and 14)
- No cleaning allowed size 10 to 16
- HUS4-HF and HUS4-AF with multilayer
HUS4-CR coatings for additional corrosion
(10) protection
- Through fastening with H, A and C head
HUS4-MAX - Pre-fastening with A head
capsule
