M4-0.7 x 75 18-8 Stainless Steel Metric Flat Head Socket Cap Screw is a 90° countersunk 18-8 stainless steel metric flat head socket cap screw for flush seating in a matching metric countersink. The head is intended to seat flush when the mating countersink is correctly prepared for the metric flat-head angle.
Guide rails and slide tracks use metric flat heads where any projection can interrupt motion or rub against a moving part. Some metric drawings call this 18-8 family A2 stainless; that is material wording, not a mechanical rating. Confirm overall length, head diameter, head height, socket size, and key engagement before substitution.
Cold Headers keeps this 18-8 metric flat head family separated from inch-series and alloy rows so purchasers can keep the drawing callout intact. Left-hand threading can be quoted for special metric flat head applications. 18-8 Metric Button Head Socket Cap Screws reduce projection without a countersink.
