Double Action Spring Release Button
(4mm Inlay Design)
Spring Release Button
Our SRB is the finest double-action spring release button that you can buy. Made from 440c stainless steel and heat treated for hard wear resistance, these push buttons offer maximum performance. This is needed in high performance switchblade making when a push button is being used to depress and hold a strong leaf spring.
This version is the 4mm inlay design, which allows you to use a standard 4mm cabochon stone or other 4mm diameter inlays. This will ad that extra touch to any D/A folder. To help you integrate these into your switchblade designs, we use simple fractional drill sizes to insure simplicity of installation.
- The button spring pocket is made with a 7/32" drill
- The counter-bore for the top-hat spring holding flange is made with a 1/4" inch drill
- The top channel is 4mm and allows easy bezel setting or glue-in installation
