DIN 1469:2011 Grooved Pin

DIN 1469:2011 Grooved Pin combines a grooved pin with a necked fitting area and is suitable for hole connections requiring holding force, location, and anti-loosening through grooves.

The groove creates local elastic or plastic engagement with the hole wall during insertion, while the necked design improves positioning and stopping. Compared with ordinary fasteners, this form places more emphasis on controllable installation, surface protection, and efficient management of matching parts for engineering projects requiring stable supply.

It is commonly used in instrument parts, light machinery, handle fixing, hinge accessories, and fixture locating. According to drawings or service conditions, groove type, diameter, material, and surface finish can be selected to improve overall fastening performance and service life.

  • What is a Bolt?

    Simply put, a bolt is a cylindrical fastener with external threads. It works with a matching nut or is screwed directly into a threaded hole of the mating part to firmly hold two or more components together. To put it intuitively, think of it as a "metal nail." However, unlike a nail that is driven in with a hammer, a ...
