Slotted Spring Pins

Additional Slotted Spring Pin Options

SPIROL has the ability to design and manufacture custom Slotted Spring Pins, however, when SPIROL is consulted early in the design stage, most applications are able to utilize SPIROL standard Slotted Pins which reduces the cost of the assembly.  For those applications that require a unique solution, SPIROL’s Application Engineers will partner with you to design and manufacture a custom part to meet your particular requirements.  By involving SPIROL early in the design stage of your project, we will develop a custom solution that will lower your overall product cost, improve product quality, simplify the assembly process and get you to market fast.

SPIROL has extensive experience in designing Slotted Pins with custom diameters, custom lengths, and other custom features, and we can manufacture Slotted Pins from special materials such as beryllium copper and 316 stainless steel to meet unique application requirements.

SPIROL also manufactures Slotted Spring Pins to meet aerospace and military standard requirements.  All pins purchased to aerospace and military specifications are supplied with the required testing and certification documentation.  See the specific aerospace and military specifications SPIROL manufactures Slotted Spring Pins to below.

Application Engineering Assistance: If you would like assistance in selecting the proper Slotted Spring Pin – including determining the proper hole size, tolerance and installation method, please Request Engineering Support!  We are here to help!
