CSK LN Bolt
Hyrax CSK LN bolts (countersunk-head sleeve anchors) give a flush, low-profile fixing into concrete and masonry. The countersunk head sits level with the surface, making them ideal where a protruding bolt head is not acceptable — door frames, fixtures and finished surfaces.
- Countersunk head sits flush with the fixed surface
- Sleeve expansion grips firmly in concrete and masonry
- All standard sizes available
- Zinc-plated mild steel and stainless steel options
