Bolt Sets for PVCu Flanges

Nuts and bolts are an essential part of any flanged PVCu pipework system, providing the clamping force required to create a secure, leak-tight joint. Designed for use with PVCu flanges and backing rings, bolt sets ensure that flanged connections remain stable under pressure and during long-term operation.

Each bolt set is supplied as a complete fixing solution for a single flanged joint, removing the need to source individual components separately. A standard bolt set includes:

• 4x Hexagon head threaded/part threaded bolts
• 4x Matching hex nuts
• 8x Flat washers

Each bolt set provides the full required parts for 4 bolt holes. As flanges get larger, the number of bolt holes increases, so ensure to take into consideration the number of bolt sets required.

The choice between bright zinc-plated and stainless steel bolt sets depends on the installation environment and the level of corrosion resistance required.

• Bright zinc-plated bolt sets are suitable for indoor installations and controlled environments where exposure to moisture, chemicals, or aggressive atmospheres is limited. They offer good strength, cost-effectiveness, and protection against light corrosion, making them a popular choice for general-purpose PVCu pipework systems.

• Stainless steel bolt sets are recommended for corrosive environments, outdoor installations, or applications involving chemicals, humidity, or frequent washdown. They provide superior corrosion resistance and are ideal for use in chemical processing, water treatment plants, and coastal or exposed locations where long-term durability is critical.

Selecting the correct material ensures the longevity of the flanged joint and helps maintain system reliability over time.
