Sink basket bolt 70 mm McAlpine BRBOLT70 for sink strainer assembly

McAlpine BRBOLT70 is a 70 mm sink basket bolt engineered to secure a sink strainer (sieve) during installation or replacement. This threaded fixing component is intended for use with ceramic, stainless steel and composite sinks where a 70 mm fixing length is required. The bolt provides a straightforward mechanical connection between the strainer body and the sink assembly, enabling a stable and leak-resistant fit when used with the appropriate sealing and mounting parts.

Advantages

The bolt is manufactured to provide consistent thread engagement and dimensional accuracy for reliable tightening. Its 70 mm length accommodates a range of sink thicknesses and mounting arrangements without need for custom modification. Designed for compatibility with common basket strainers, the component facilitates faster strainer replacement and reduces the need for additional bespoke fixings. The straightforward design makes it suitable for professional plumbing repairs as well as DIY maintenance.

Suitable for

• Replacing a damaged or corroded sink strainer bolt
• Installing a new basket strainer in kitchen sinks
• Securing strainers in ceramic, stainless steel or composite sinks with up to 70 mm fixing depth
• General plumbing repair and maintenance tasks involving sink fixings

Key specifications

• Fixing length: 70 mm
• Threaded bolt designed for sink basket/strainer assemblies
• Compatible with ceramic, stainless steel and composite sink materials
• Used as a mechanical fixing between strainer body and sink

How to use

Fit the sink basket bolt through the strainer body and the sink from above, ensuring the sealing washer and any required gaskets are correctly positioned to prevent leaks. From beneath the sink, engage the threaded nut or retaining component and tighten evenly until the strainer is held firmly in place. Avoid over-tightening, which can damage sink materials or deform sealing elements. Verify alignment and sealing before completing the installation and running water to check for leaks.

Usage recommendations

Use compatible washers and sealants designed for sink strainers and follow manufacturer guidance for torque or tightening. For thick or unusual sink constructions, measure the required fixing depth before installation to confirm that the 70 mm bolt provides adequate engagement. Replace corroded or damaged bolts promptly to maintain a secure, leak-free connection.
