Knurled Thumb Nuts A1 Stainless Steel Threaded Nut (4, M5 / 5mm 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 5mm and a 20mm 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. 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 4 – PERFECT FOR 3D PRINTERS, PANEL WORK & PRECISION INSTRUMENTS Each pack contains 4 x M5 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 M5 threaded bolts, studs, or rods. Compatible with all standard M5 x 0.8mm coarse pitch metric fasteners.
