C.S. Osborne’s LOXX® self-locking, quick-release two-part engineered fasteners are strong and versatile. Once the male lower and female upper parts are locked, the only way to release the fastener is to pull up on the upper cap where there is an internal tension spring to control the action when locking and releasing. Available in high-grade brass and stainless steel in many finishes, variations and styles. Can be used on both hard and soft materials and can replace all types of fasteners. Easy installation with applications for marine, golf carts, tents, awnings, leather goods, architectural, industrial and more.
