These flanged button head screws solve all three problems in a single fastener, with a wide choice of materials and finishes to match your application.\u003c\/p\u003e\n    \u003cp\u003eEach screw features an integrated flange beneath the button head, acting as a built-in washer for improved load distribution. Available in five material and finish combinations — Stainless Steel (with or without pre-applied thread-locking glue), Carbon Steel with Black Zinc, Carbon Steel with White Zinc, and Carbon Steel with Bright Nickel plating. Sizes range from M2 × 5 mm (approx. 3\/16″) up to M5 × 15 mm (approx. 19\/32″), with both Allen (hex socket) and Torx drive options depending on variant.

Measure the thickness of the material being fastened and add any required thread engagement depth in the receiving part. For example, an M4 × 8 mm screw is typically used for panels up to 6–7 mm thick with a tapped hole below.
