Available with shank drilled for cotter pin or undrilled for stop nut application, and with or without drilled head for safety wire.

It’s a bolt. Works good. Lasts a long time
Although the bolts came from three different places, in 3 different shipments, they all arrived on time and were all correct. Whatever system you used to pull that off seems to be working.. Thanks,

Great service on a great a product line.
Bolt was as advertised and is working great.
as usual.
The grip and thread length needed was unusual and not available locally. There were plastic sleeves protecting the threads during shipment, nice touch. The bolts fit perfectly!
