Set screw M4 x 5 mm

Set screw M4 x 5 mm, small, unobtrusive, but pretty crucial

It’s easy to overlook, but when it’s missing, you notice immediately. Our M4 x 5 mm set screw is made precisely for those moments when a small, precise fastener needs to hold, clamp, or secure reliably without drawing attention.

Precise M4 thread for clean connections

The set screw has a cleanly manufactured M4 thread that is easy to start and engages firmly. This lets you securely fasten components, clamp shafts, or adjust small mechanisms without feeling like the thread is about to strip. Especially with repeated loosening and tightening, a properly cut thread pays off: it runs smoothly, grips well, and ensures a stable connection.

Stud-screw design for concealed fastening

This set screw is a headless stud that disappears completely into the thread. Ideal when you need a flush or nearly invisible fastening, for example in couplings, clamping blocks, shaft collars, or small housings. Thanks to its compact design, you can also use it in tight, hard-to-reach areas where a normal screw with a head would simply be too bulky.

Stainless steel for long-term use

The set screw is made from high-quality stainless steel that proves very robust in everyday use. The material is corrosion-resistant, so you can use it in damp environments, in the workshop, in your hobby room, or outdoors in covered areas without it developing surface rust right away. In the long run, this means: less replacement, fewer problems, and a calmer working experience.

Dimensions 4 x 5 mm, compact and versatile

With an M4 diameter and a length of 5 mm, you’re choosing a very common, practical size that appears in many constructions and repairs. Short enough not to get in the way, but long enough to hold securely. Whether you’re retrofitting something, tightening up a loose connection, or implementing your own small project, this dimension fits surprisingly often.

Typical applications, from precision mechanics to DIY

You can use the M4 x 5 mm set screw, for example, in shaft collars, clamping bushings, model-making components, small machines, or custom brackets. Wherever you want to positively lock a shaft, pin, or component in place without a screw protruding on the outside, this stud screw is a very practical choice. Many people also use such set screws to secure stops, end positions, or fine adjustments so that nothing shifts on its own.

For everyone who likes things neatly assembled

If you value clean, tidy constructions where nothing sticks out and everything is in its place, this set screw is a good addition to your range of fasteners. It is small, straightforward, functional, and designed precisely to do its job reliably in the background while your project shines in the foreground.
