Assembly pins are certainly not a new invention but JW Winco has taken this universal standard part and improved it. The standard parts specialist has been able to enhance developed parts, according to an application, and combine them with other standard securing parts.
Stainless steel assembly pins from Winco’s GN 2342 series are available in all common diameters — from 8 to 20 millimeters and in various standardized lengths. Three different end-washer forms and the selection of a specific code number between the assembly pin — with and without transverse spring cotter pin holes — diversifies the series even further.
On one of the end washers is a simple, turned stainless steel collar washer that holds an axially inserted assembly pin in the correct position in the hole. The eyelet washer version, having a hole where a retaining cable or a ball chain can be attached, protects the assembly pin from getting lost. Additionally, the matching spring cotter pin secures the assembly pin axially, through the transverse hole.
Another type of washer offers a fastening tab with an elongated hole. This simultaneously secures the assembly pin axially, which restricts rotation and is attached without play using a countersunk screw.
All of washers offered by JW Winco are non-detachable because they are fastened to the assembly pin via their axial countersunk hole. This design favors the implementation of solution-specific special lengths that are available upon request in comparatively low quantities.
Both of the GN 2344 series washers, with protection against loss, can be ordered separately for individual applications. For example, this could include additional retaining cables or for specific assembly pins. The securing element, which is available as GN 1024, is based on even-numbered wire gauges (unlike the DIN standard), which simplifies matching to the associated through hole.
The spring cotter pins are available in steel and stainless steel, as well as with single or double winding. With the latter form, the flat spring characteristic curve facilitates easy fitting.
