Steel Door Latch Mounting Plate

After a technical review of the performance requirements, SPIROL Engineering recommended its standard Series FH300 Flat Headed Helical Knurled Pin that would provide maximum pullout resistance, and could easily be fed and oriented, facilitating automated assembly with a relatively simple installation machine.

SPIROL’s Headed Knurled Pins provide an excellent alternative to screws when simplification of assembly is desired and permanent assembly is acceptable. The customer’s host material of die-cast zinc is an ideal match for SPIROL’s low carbon steel pin. Since this component would not be exposed to significant atmospheric corrosion, SPIROL recommended our most cost effective surface treatment for mildly corrosive environments of phosphate and rust preventive oil coating. This surface treatment offers 72 hours to base metal corrosion.

SPIROL offered the customer the ideal permanent joining solution and recommended both the hole depth and hole diameter in order to maximize pin performance and component longevity over the life of the application. Furthermore SPIROL’s solution can be easily automated offering optimum manufacturing efficiency and lowering the total installed cost of the door latch assembly.

Our staff of engineers will review your application needs and work with your design team to recommend the best solution.
