HEINRICH KIPP WERK has developed a locking pin that meets increased hygiene requirements. Its construction according to hygienic design guidelines prevents dirt particles from adhering and simplifies cleaning processes. This makes the locking bolt ideal for the design of machines and systems used in industries such as food, pharmaceuticals and medical technology.

Locking pins enable fast adjustment of moving machine components. Usually, a pin is pulled out of its counterpart with the help of its pull knob or ring to securely move and lock machine parts into a desired position. KIPP is now presenting a design component in hygienic design for areas of application in which cleanability plays an important role. The new locking bolt, made of high-quality 1.4404 stainless steel, has a tapered collar so that the screwed point can be hygienically sealed with the associated sealing washers and washers. The surface of the structural component with a roughness depth of Ra < 0.8 µm prevents dirt particles from adhering. In addition, the locking bolt is suitable for CIP/SIP cleaning processes.

The new locking bolt in hygienic design made of FDA-compliant materials is resistant to polar and non-polar media as well as aromatic substances. It is available in versions with or without locking groove and with hardened or non-hardened locking pin. The locking pin is available with pin diameters of 6 and 8 mm and with screw-in threads in sizes M10 and M12 with regular and fine threads. Its shaft seal is optionally available in 70 EPDM 291 (black) or 75 Fluoroprene® XP 41 (blue). A matching Hygienic USIT® K1491 seal and washer made of the same basic materials is included in the scope of delivery and can also be obtained as an accessory if required.
