Joining Parts with SnapLock™

Solution Bulletin

The Problem:

Many fabricating jobs require the joining of parts. Typically, fabricators use fasteners (screws, rivets) or welds to do so. While effective, they add secondary operations and material costs to the job. Joining parts doesn’t necessarily require fasteners or welds. Applications are available that can help lower manufacturing costs and speed time to delivery. 

The Mate Solution:

Mate Precision Technologies developed SnapLock™ for just such a purpose. SnapLock allows fabricators to join parts, even if they are of dissimilar type and/or thickness. SnapLock eliminates expensive secondary operations such as spot welding, riveting or fastening with threaded hardware. With SnapLock, fabricated assemblies can be created efficiently and effectively with CNC precision.

SnapLock is a Lance and Form assembly that provides a self-locking, spring loaded tab that snaps securely into a pre-punched hole. When engaged with a hole in the receiving tab, the small button provides a positive mechanical lock. It can also be removed, if needed. An optional reinforcement rib is available for joining 16 gauge(1,50mm) or thinner materials.

Benefits include:

  • Precision joint placement with CNC accuracy
  • Assembly done in press brake
  • Parts attached by hand in assembly
  • Form placement can be inside or outside
  • Eliminates or minimizes fasteners
  • Joins dissimilar material types, such as stainless steel and aluminum
  • Joins dissimilar material thicknesses
  • Eliminates expensive secondary operations
  • Fabricate and assemble pre-painted material

Besides joining parts, customers have used SnapLock in a wide variety of ways including:

  • Easing downstream assembly
    • Eliminate tools and hardware
    • Eliminate welding
  • Locators for precise parts fit
  • Joining materials where welding is not possible, such as metal and PVC
  • Use on prepainted materials where hardware or welding could mar surface
  • Shelf locators for metal furniture
