Questions & Answers

Is this a genuine original part?

This is a premium quality aftermarket replacement part from J Clarke Marine, manufactured to meet 316-grade marine standards, ensuring it outperforms standard factory plastic fittings.

How do I know if it is compatible?

Compare the dimensions (19mm top / 12.5mm height) with your existing fittings. If you are using standard 6mm or 8mm shock cord, this "Type A" mushroom button is the industry standard fitment.

What size screw should I use for installation?

A No. 8 (4.2mm) countersunk 316 stainless steel screw is recommended. The 4mm hole is designed to provide a snug fit for standard marine-grade self-tapping screws.

Note: 4boats.co.uk recommends verifying the mounting surface thickness before choosing your screw length. Ensure use of 316 fasteners to maintain the corrosion resistance of the button.
