2 Pieces Stainless Steel Rigid Shaft Coupler 5mm x 8mm for 3D Printers

This set includes two rigid shaft couplers made from 304 stainless steel, offering resistance to rust and wear. Each coupler has a 5 mm diameter, an 80 mm shaft length, and a 5x8 mm coupling size. The metal cylindrical body with side set screws ensures a secure connection on rotating shafts. Designed for direct-drive connections, it minimizes backlash in precision setups like 3D printers. Suitable for makers and hobbyists for small mechanical builds and model equipment.
