Our products provide total protection to bolted connections
How our product works
They provide protection from cellulosic, hydrocarbon and jet fire scenarios matching the fire protection ratings of the main structure and are available in a large range of metric and imperial sizes with a speedy tap on fitting, meaning they can be applied to bolt heads and nuts in any weather. They also provide protection against corrosion.
Standard bolt caps are sized for a range of bolts meeting different specifications. There are also bolt caps for tension control bolts (TCB’S), custom shapes & sizes, split caps (for difficult access areas), screw caps (for ease of cyclic bolt inspection) and caps with extension pieces to accommodate double nut fittings, excess threads or large anchor bolts on storage vessels that need regular inspection.
Supply is available globally direct in bulk or via distributors.
Interchar and Chartek bolt caps are supplied globally in conjunction with and on behalf of AKZO Nobel.
Re-usable masking plugs are also available to make the process more productive.
Bolt Cap Technical Data
The Bolt Cap is a passive fire protection shroud providing both fire protection and corrosion protection to bolted connections. The bolt cap has been tested to a range of cellulosic, hydrocarbon and jet fire threats as well as being tested for a 1000 hours to ASTM D117 for corrosion protection. Bolt caps have been assessed and approved by a number of bodies, including the Steel Construction Institute, the Danish Fire Institute, Warrington Fire and leading global engineering companies.
Bolt Cap H&S Data
No special precautions are necessary when using bolt caps. Reasonable care should be taken when installing to avoid contact with the internal clips. Bolt caps are manufactured from a specially formulated compound which is stable and inert under normal atmospheric conditions. When subject to prolonged exposure above 1,200 degrees C the Cap will very gradually harden leaving a grey product form. Bolt Caps may be disposed of as normal household waste where permitted by the Local Authority.

Quick-Fit Fire & Corrosion Protection
Simple, Secure Installation
Each bolt cap is designed with three internal clips that align with the six flat surfaces of the bolt head, ensuring a snug and secure fit. Installation is straightforward: simply position the cap so the clips are aligned, then tap it into place with a rubber mallet. The process is quick, requires no special tools, and can be carried out in all weather conditions.
Reliable Long-Term Protection
Once fitted, the caps lock firmly over the bolt head or nut, shielding it from fire, corrosion, and environmental exposure. The design ensures a consistent, long-lasting fit while still allowing access for inspection when required.
