Reliable M4 Knurl Nut made from 304 stainless steel with DIN466 profile, 0.7mm thread pitch, and compact 16mm x 8mm x 9.5mm dimensions for adjustable fastening and mechanical assemblies.
$2.29
The M4 Knurl Nut is a compact hand-adjustable fastener used in 3D printers, jigs, fixtures, brackets, panels, machine guards, test setups, electronics mounts, and custom mechanical assemblies. This nut features an M4 thread, 0.7mm thread pitch, DIN466 profile, and 304 stainless steel construction for durable everyday hardware use.
Unlike a standard hex nut, a knurl nut has a textured outer edge that can be easier to grip by hand. This makes it useful for assemblies that may need occasional adjustment, removal, repositioning, or tool-free tightening. The M4 Knurl Nut is a practical choice for makers, machine builders, 3D printer owners, and fabricators who need a clean stainless steel fastener for small mechanical projects.
This knurl nut uses an M4 thread with a 0.7mm pitch. It should be paired with compatible M4 screws, threaded rods, studs, or other matching metric hardware. Before installation, confirm thread compatibility and avoid forcing the nut onto damaged, dirty, or mismatched threads.
The DIN466-style knurled profile provides a round hand-adjustable shape with a textured outside surface. This can be useful in fixtures, removable covers, clamp points, small adjustment mechanisms, access panels, and machine assemblies where quick hand operation is preferred over a standard wrench-tightened nut.
This product is made from 304 stainless steel, offering a clean and durable hardware option for many indoor workshop, printer, fabrication, and light machine applications. Stainless steel is useful where corrosion resistance and a finished hardware appearance are important.
The M4 Knurl Nut can be used in 3D printer upgrades, enclosure panels, removable covers, light-duty clamping points, brackets, tool holders, robotics projects, small machine assemblies, and custom fabrication projects. It is especially useful where the nut may need to be adjusted or removed by hand during setup or maintenance.
The listed dimensions are 16mm x 8mm x 9.5mm. Before final installation, confirm that the nut clears nearby brackets, panels, printed parts, guards, belts, moving parts, or electronics. Hand-adjustable fasteners work best when there is enough surrounding space for a comfortable grip.

DIN466 knurled nuts are commonly used for hand-operated clamping, adjustment, and fastening applications. For general metric thread reference information, see this metric thread size reference.

Before installing the M4 Knurl Nut, confirm that the screw, threaded rod, stud, or mating hardware uses a compatible M4 thread with 0.7mm pitch. Mismatched thread sizes can damage the nut or mating hardware.
Thread the nut on by hand at first. If it does not turn smoothly, stop and check for thread damage, debris, misalignment, or incorrect hardware. Do not force the nut onto a screw or stud.
Knurl nuts are useful where hand adjustment is desired. Tighten only enough for the application. Excessive force can damage softer materials, crush 3D printed parts, distort thin panels, or make removal difficult.
If the nut is clamping against plastic, acrylic, wood, printed parts, painted surfaces, or thin sheet metal, use a washer where appropriate to spread the load and protect the surface.
Before final installation, confirm that the knurl nut does not interfere with belts, pulleys, fans, wires, linear motion parts, panels, or machine travel. The larger hand-grip shape may need more clearance than a standard hex nut.
Keep the internal thread and mating hardware free from chips, dust, adhesive, paint, rust, or debris. Dirty threads can make the nut difficult to install and may cause galling or thread damage.
Wipe stainless steel hardware with a clean dry cloth during assembly. Avoid harsh chemicals or abrasive tools if the visible finish matters. In damp or dirty environments, inspect periodically and clean as needed.
