Precision and Protection: Bolt Kits for Pipework Systems
Bolt kits play a vital role in the safe and secure installation of pipework components. At Stourflex, our bolt kits are carefully assembled to ensure compatibility with our full range of rubber bellows, expansion joints, pump connectors and air dirt separators. Each nut and bolt kit includes the necessary bolts, nuts and washers required to carry out reliable installations in line with system specifications, helping engineers avoid delays and improve on-site efficiency.
A bolt kit typically contains a matched set of components designed to withstand the pressures and demands of chilled water and heating systems. Whether you are connecting pipework for a commercial HVAC installation or maintaining high-pressure hot water systems, the right bolts, nuts and washer assortment kit will safeguard performance and system integrity. Compatibility is critical, particularly in systems where safety, pressure ratings and regulatory compliance must be considered.
Why Use Bolt Kits in Building Services and HVAC Installations?
Bolt kits are used widely across mechanical and building services installations. Our kits provide an assured means of connecting pipework accessories, including our rubber bellows, expansion joints, pump connectors and air dirt separators, which require secure and durable fixing methods.
Bolt kits for sale from Stourflex are particularly popular in the heating and cooling sectors, where contractors rely on dependable fittings that align with pressure and temperature requirements. For chilled water and heating installations, choosing the correct nut and bolt assortment prevents operational risks and supports ongoing system resilience.
Best Practice Installation Guidance
Correct installation begins with selecting the right kit. Stourflex offers bolt kits in a range of sizes to suit DN32 to DN300 pipework. Our product range includes:
- M16x60 for PN06 (DN80-100), PN10 (DN32-65) and PN16 (DN32-65)
- M16x70 for PN06 (DN125-200), PN10 (DN80-125) and PN16 (DN80-125)
- M20x70 for PN10 (DN150-200) and PN16 (DN150)
- M20x80 for PN10 (DN250-300) and PN16 (DN200)
- M24x80 for PN16 (DN250-300)
We always recommend following the correct tightening sequence and torque settings, particularly when securing flanged components such as our expansion bellows. Even tightening distributes pressure evenly, reducing the likelihood of leaks or mechanical stress. Avoid over-torquing, misalignment or mixing different grades of steel within the same assembly.
