SJ3542

The 3M SJ3542 Dual Lock Reclosable Fastener is engineered for robust attachment solutions. It utilizes polyolefin stems with mushroom-shaped tops that interlock when snapped together, creating a strong and reliable fastening system. This fastener is available in various stem densities, including 170, 250, and 400 stems per square inch, allowing for adjustable closure strength based on application needs.

Designed for ease of use, the SJ3542 offers features such as easy alignment, as the stems can engage in any direction. It provides a positive locking mechanism with an audible snap, assuring a secure closure. The reclosable nature allows for multiple open/close cycles, contributing to a high cycle life. Blind attachment is also possible, where the fastener can be applied to the backside of a substrate without affecting the show surface.

This fastener is suitable for applications requiring a rattle-free connection and can simplify assembly processes by allowing components to be attached before final assembly, potentially reducing part count and assembly time without the need for tools. Pressure-sensitive adhesive options are available for easy application, or non-adhesive backed versions can be used when PSA is not suitable.
