A4 316 Stainless Steel Through Bolt Anchors

Through bolt anchors are designed for use in concrete or dense natural stone with a strength greater than 20N/mm2 and are probably the most widely used fixing bolt in today's market.
The through bolt requires a hole in concrete the same diameter as the bolt, thus allowing the hole to be drilled through the fixture avoiding lengthy marking out procedures.
To prevent damage to the spring clip the fixture hole should be 2mm greater than the fixing hole.
Through bolts are a versatile, cost-effective anchor combining ease of installation with good load carrying capabilities.
When selecting any fixing bolts the following factors must be considered.

• Thickness of fixture including any packing
• Non-structural screed must be included in the fixture thickness
• Compressive strength of concrete
• Distance from any edge
• Centre to centre distance of anchors
• Type and direction of load applied.

Often referred to as ‘Marine Grade’, A4 316 stainless steel offers some of the highest levels of resistance against corrosion and tarnishing making it ideal for use in marine or corrosive environments. It is identical in appearance to A2 stainless steel and retains all the same benefits, but offers an even greater levels of rust resistance.
