Knurled Dowel Pin Straight Knurl Color Plating Manufacturer

Knurled dowel pin hold together parts of an assembly with friction. They may also be used as location pins. These pins are common in the automotive and aerospace industries as well as in furniture making. The knurled dowel pin provides strength when you secure your materials. A metal cotter pin can be bent during installation to act as a staple or spring pin. A hitch pin assembly ensures that your trailer is secure by dropping the pin in place and locking. A steel-grade, industrial safety pin locates, aligns, and safely secures components. Ever Hardware provides custom-made fasteners and customizable packaging.

Knurling is a manufacturing process, typically conducted on a lathe, whereby a pattern of straight, angled or crossed lines is cut or rolled into the material. The operation is performed for producing indentations on a part of a workpiece. Knurling allows hands or fingers to get a better grip on the knurled object than would be provided by the originally smooth metal surface. Occasionally, the knurled pattern is a series of straight ridges or a helix of “straight” ridges rather than the more-usual criss-cross pattern.

Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate’s surface integrity as it is formed. Indeed, the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers. The majority of hardware parts are zinc-plated, rather than cadmium-plated.
