Dowels are solid pins, usually precision ground to narrow limits to permit accurate fitting. Precision dowels are traditionally used to hold parts together in a fixed alignment relying on the tightness of fit to stay in place. Our stocked range includes stainless steel A2, stainless steel A4, mild steel unhardened and through hardened steel to ISO and DIN standards. All our dowel pins are made to a high quality and we offer up to 60% discount on volume orders, plus FREE shipping* on all orders over £50.
