M6x075

M6x075, commonly written as M6 x 0.75, designates a metric screw thread with a nominal major diameter of 6 millimeters and a thread pitch of 0.75 millimeters. It is part of the ISO metric thread system and represents a fine-pitched variant within the M6 series; the standard coarse pitch for M6 is 1.0 mm.

The thread form is 60 degrees, and the designation applies to external threads (bolts) and their corresponding internal threads (nuts or tapped holes) with the same pitch. In general-use fastener practice, tolerance classes such as 6g for external threads and 6h for internal threads are common, though exact tolerances depend on the component specification and regional standards.

Applications and usage are common in small fasteners where a finer pitch provides smoother engagement and greater adjustment precision. M6x0.75 bolts and nuts are widely used in electronics enclosures, automotive components, machine assemblies, and various consumer and industrial devices.

Materials and variants are similar to other metric fasteners, with options including carbon steel, stainless steel, and coated or plated finishes. Non-metallic options exist for specialized applications, though metal fasteners remain dominant for M6x0.75.

Notes for sourcing: some manufacturers may print the designation as M6x075 or M6x0.75 without a space or decimal clarity. Always verify the pitch and thread class (external vs. internal) to ensure proper mating with mating parts.
