About the 93395A218 Hex Socket Countersunk Screw M3x35
This 93395a218 screw hex skt csk item is an M3 hexagon socket countersunk head screw at a 35 mm nominal length, made to DIN 7991 (EN ISO 10642) with the 90 degree flush-seating head. At 35 mm it is the longer sibling of the 30 mm reference in the same range, giving an extra 5 mm of reach for a deeper plate stack, an added spacer or a thicker gasket while keeping the same M3 coarse thread and the same flush head profile. The material is 316 stainless steel, a molybdenum-bearing austenitic grade specified where chlorides, salt water or cleaning chemicals would attack a plated carbon steel screw or stain a 304 one. Long, small-diameter screws like this are relatively slender, so tightening torque should be set to the fastener rather than to the feel of the hex key.

Typical applications
The 35 mm length is chosen when the fastener has to cross a deeper build-up – stacked standoffs, a thick sealing gasket, or an insulating layer between a cover and its frame – and still engage the tapped hole below. As with the shorter variants, the flush head keeps the outer face clear for seals, sliding covers and hand contact. The 316 grade suits outdoor, coastal and wash-down installations without additional plating.
