8G x 16 mm Wafer Head Self-Drilling Screw, 304 Stainless Steel - WDSA2M42X16

The Wafer Head Self Drilling Screw A2 (304) is a wide, low-profile wafer head screw with a drill point. The drill point drills its own hole and forms the thread, and the wide head gives a large bearing area on thin sheet.

A2 stainless (grade 304) gives sound general corrosion resistance for inside work, fresh water and ordinary outdoor exposure. It is not the grade normally chosen for coastal, pool or marine work, where A4 (316) is recommended. Gauge sizes are shown as a number followed by G. On this range 6G is 3.5 mm, 8G is 4.2 mm, 10G is 4.8 mm, 12G is 5.5 mm and 14G is 6.3 mm, as listed by the supplier.

You can choose from 24 variants, covering sizes 8G to 12G and lengths 13 mm to 50 mm. Variants are supplied in packs of 500 to 1000, depending on size.

Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. In wet conditions, keep stainless steel apart from aluminium and galvanised steel with a washer or sleeve, to reduce the risk of galvanic corrosion.

Key specifications

Selecting the right option

Sizes are shown as gauge (G) with the metric size where the supplier lists it. Self-drilling screws are intended for thin sheet and light framing, and the drilling capacity is not stated in the supplier data, so check it against the material thickness before use.
