• Outdoor seating
• Handrails
• Barriers
• Warehouse racking

Through bolts are an ideal fixing to be used to attach medium to heavy duty objects to concrete.

There is a range of through bolt fixings to suit a variety of applications such as:

• Steel through bolts
• Stainless steel through bolts
• BZP through bolts
• Galvanised through bolts
• Hanger through bolts

• Before attempting a through bolt fixing it is essential that you identify the drill bit size you need and the depth of the hole required
• Once this is established, a hole can be created using the drill ensuring that any dust and debris is cleaned out ready for the anchor to be inserted
• Next screw the washer on to the top of the through bolt until it is flush with the bolt
• Insert the through bolt into the hole, giving it a gentle tap with a hammer if required until it reaches the end of the hole
• Once inserted you can begin tightening the nut on the anchor until you it clicks. Be careful not to add too much torque as this can effect the quality of the fixing.
• Finally remove the nut and washer and the through bolt will be ready to use

ETA refers to European Technical Assessment and is given to fixings that pass certain high-level durability tests. Options 1-6 tend to be for through bolts and fixings that can be used with cracked concrete, whereas 7-12 is for through bolts that can be used with non-cracked concrete, with option 7 being the highest level.

Through bolt fixings are not designed to be removed once inserted as this can cause damage to the base material and can create a hole. However, if required the anchor can be sawed off with a hacksaw.
