Working on a project that needs precise alignment? These uxcell dowel pins are your best friend. They're split spring pins (also called roll pins or spring dowel pins) made from stainless steel, so they're corrosion-resistant and strong. The size is M5 x 40mm, which means they have a 5mm diameter and are 40mm long. The inner diameter is about 3mm, and they have a 1mm wide slot – that split design lets them compress slightly when driven into a hole, creating a tight, secure fit that won't easily work loose from vibration. You get 10 pins in the pack. They're perfect for use in jigs, fixtures, machinery, press tools, or any DIY project where you need to align two parts accurately. A simple, essential hardware item for any serious toolbox. Just make sure you have the right size drill bit for a proper fit!
