M3 Countersunk Socket Screws – A4 Marine Grade Stainless Steel, Allen Key, Metric

These are top-quality M3 countersunk socket screws from GWR Fasteners, made right here in the UK.

They're crafted from A4 marine grade stainless steel, which means they're highly resistant to corrosion—perfect for boats, outdoor projects, or any application where rust is a concern.

The head style is countersunk, so they sit flush with the surface, and they're driven with an Allen key.

Available in various lengths, so you can pick what you need.

Brand new and metric, as expected.
