Flange Button Head Bolt Sets M3–M8 — A2 Stainless Steel

Why choose these A2 flange button head bolt sets

Each kit pairs a flange button head bolt with a matching flat washer and your choice of nut — a one-piece supply for general bolted joints. The integrated flange under the button head spreads load and prevents marking on the workpiece, while the low-profile dome gives a tidy finish. A2 stainless steel handles interior, workshop and light outdoor use without rusting.

Sizes available

Bolt diameters M3, M4, M5, M6 and M8 across thirteen length options from 10mm up to 100mm. A nut-only option in M3 is also stocked for replacements or specialised assemblies.

Pack options

Choose your nut style — wing nut for hand-tightening, nylon lock nut for vibration resistance, or full hex nut for standard joints — in single sample, 2-pack or 5-pack quantities. Mix sizes and styles to qualify for free UK delivery on orders over £20.

Typical uses

Equipment panels and enclosures, AV racks and mounts, machinery covers, garden furniture, bicycle and motorcycle brackets, indoor signage, exhibition stand building, and any application where a flanged head reduces the need for a separate washer on softer materials.

How to fit

Drop the bolt through the workpiece and run the chosen nut down the thread by hand. The button head drives with a hex (Allen) key against the chosen nut on the back side. Wing nuts allow tool-free release for covers that are removed regularly; nyloc nuts give vibration-proof retention.
