- RRP
- £64.15
This M20 x 220mm throughbolt anchor is manufactured in A4 stainless steel (316 grade). The bolt is passed through the fixture into a drilled hole; tightening the nut draws a tapered cone into the expansion sleeve, gripping the sides of the hole and giving high pull-out resistance in solid material.
Typical applications
- Structural fixings into concrete and solid masonry
- Machinery mounting, racking, and balustrades
- Handrails, gates, and external metalwork
- Site fixing where a heavy anchor is required
Available singly and in packs of up to 5, with free next working day delivery on UK orders over £50 and 30-day returns.

How do I choose between A2 and A4 stainless steel?
A2 (304) stainless steel suits most indoor, outdoor and workshop jobs. Choose A4 (316) marine grade for coastal, marine, poolside or other chloride-rich environments.
How do I make sure I order the right size?
Check the size in the product title and the standard, material and dimensions in the Product Specification tab. In M8 x 30, M8 is the thread diameter and 30 is the length in millimetres. See our size guide if you need more help.
