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 affect the quality of the fixing.
• Finally remove the nut and washer and the through bolt will be ready to use

The zinc and yellow passivated covering is similar to galvanised or zinc plated covering. However, zinc and yellow passivated through bolts ensures that the fixing will remain resistant to corrosion whilst adding an aesthetically pleasing element.

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.
