Knurled Thumb Nuts A1 Stainless Steel Threaded Nut (10, M3 / 3mm Thin Type)

A1 STAINLESS STEEL – CORROSION RESISTANT, STRONG & VIRTUALLY NON-MAGNETIC Manufactured from A1 grade stainless steel, these M5 thin type knurled thumb nuts offer excellent resistance to corrosion, moisture, and chemical exposure, combined with good tensile strength and a clean machined finish. A1 stainless is also virtually non-magnetic — an important property for electronic, laboratory, and scientific instrument applications where magnetic interference must be minimised. Unlike plated steel alternatives, these nuts will not rust, pit, or discolour over time. DIN 467 THIN TYPE – LOW-PROFILE DESIGN FOR SPACE-CONSTRAINED ASSEMBLIES Precision-manufactured to the DIN 467 thin type standard with an overall height of just 3mm and a 12mm outer diameter, these nuts are specifically designed for applications where axial space is limited. The shallow profile allows secure hand-tightened clamping in tight panel gaps, instrument housings, 3D printer frames, and machine enclosures where the higher-profile DIN 466 variant would protrude or interfere with adjacent components. Type DIN466, Thin Type DIN467 KNURLED GRIP SURFACE – FAST, SECURE TOOL-FREE TIGHTENING The precision diamond-knurled outer circumference provides a firm, confident grip for rapid hand tightening and loosening without any tools. The knurl pattern maintains reliable grip even with oily, damp, or gloved hands — making these ideal for high-cycle adjustment applications where speed and convenience matter. Through-hole threading allows full engagement along the entire stud or bolt length for maximum holding strength. PACK OF 10 – PERFECT FOR 3D PRINTERS, PANEL WORK & PRECISION INSTRUMENTS Each pack contains 10 x M3 DIN 467 thin type knurled thumb nuts — a practical quantity for 3D printer bed levelling systems, machine panel fastenings, electronic enclosures, laboratory and scientific instruments, jigs, fixtures, and any precision assembly requiring tool-free manual adjustment on M3 threaded bolts, studs, or rods. Compatible with all standard M3 x 0.5mm coarse pitch metric fasteners. UNIVERSAL M3 THREAD – COMPATIBLE WITH ALL STANDARD M3 METRIC FASTENERS With a standard M3 x 0.5mm coarse pitch right-hand through-hole thread, these thin type thumb nuts are a direct fit on all M3 metric bolts, machine screws, threaded inserts, and studding across all major brands and standards. If you need other sizes — M2, M2.5, M3, M4, M6, M8, M10 — or the High Type DIN 466 variant, our complete knurled thumb nut range covers every common metric thread in both thin and high profile configurations.
