Product description
Forgefix Lightning Bolt, hex head M10 x 100mm – box of 50. A screw-in masonry bolt that fixes into concrete and brick with no plug and no expansion force.
The Lightning Bolt cuts its own thread straight into a drilled hole – just drill and tighten. Because it's a non-expansion fixing, it won't blow out an edge, so you can fix close to corners and space fixings tightly where an expansion anchor would crack the masonry. Salt-spray tested to 1,000 hours for corrosion resistance.
- Size: M10 x 100mm
- Head: hex
- Type: non-expansion masonry bolt
- Pack: box of 50
- Corrosion: salt-spray tested to 1,000 hours
Drill the correct-diameter hole to depth, clear the dust, then drive the bolt home with a socket. With no expansion force it can be undone and re-used within reason. For timber-to-masonry, add a penny washer under the head. The M10 x 100 covers medium fixings; heavier work steps up to the M12 Lightning Bolt.
