M2.9×9.5 Philips Button Head with Washer, Self-Tapper Screw, Stainless Steel A2/A4 — BOLTON SKU 72505.
About the M2.9×9.5 Philips Button Head with Washer
This is a small self-tapping screw with a domed button head formed over an integral washer face. The m2 9×9 5 philips button head profile stays low and rounded so it does not snag, while the washer face spreads clamping load over a wider footprint than a plain button head — useful in thin sheet, plastics and soft panels where a narrow head would dish the material or pull through. The cross-recess Phillips drive suits both hand and powered drivers. Nominal thread diameter is 2.9 mm and nominal length is 9.5 mm, and the screw is offered in stainless steel to A2 or A4 grade: A2 for general indoor and dry-environment use, A4 for coastal, marine and chemically aggressive environments where added pitting resistance is needed. The exact thread form and point style should be confirmed against the drawing or sample at quotation.

Typical applications
Screws of this size are used to close sheet-metal enclosures, fix trim and cover panels, mount cable-management fittings and retain lightweight brackets, where the fastener must bite into thin material without a pre-tapped hole. The washer-faced button head suits soft or coated panels that would otherwise show witness marks, and the stainless grade options let the same fastener be used indoors or in a salt-laden coastal environment.
