M2.5×20 Phillips Round Head Screw, Stainless Steel — BOLTON SKU 72491.
About the M2.5×20 Phillips Round Head Screw Stainless
This is a small metric machine screw with an M2.5 thread and a 20 mm shank length, driven by a Phillips cross recess and finished with a round head. At M2.5 the screw sits at the small end of the metric range, where a 20 mm length gives a comparatively long grip for the thread diameter — useful when fastening through a stack of thin panels, standoffs or spacers rather than into a single thick part. Stainless steel is specified for corrosion resistance. As a m2 5×20 philips round screw the round head presents a domed bearing face that spreads load over a slightly wider area than a countersunk head and does not require the mating part to be counterbored. Exact head dimensions, stainless grade, thread pitch and any governing standard should be confirmed at quotation stage, as several head profiles are sold under the round-head description.

Typical applications
Screws of this size are used to assemble light enclosures, mount small printed circuit boards and brackets, and secure covers, labels and cable-management hardware. The 20 mm length in an M2.5 thread is typically chosen where the fastener must pass through spacers or a layered assembly before engaging its thread. Stainless construction suits humid, coastal or wash-down environments where a plain steel screw would corrode.
