The Mustad Plug 11 S (also known as the P-11 S) is a tungsten carbide drive-in stud designed to provide enhanced traction for horses on ice, snow, mud, and pavement. It is specifically intended for smaller ponies, lightweight hunters, and thoroughbreds in training.

Key Specifications:
Dimensions: Features a 10mm head diameter and sits approximately 7.5mm (1/4") above the shoe.
Material: Built with a durable tungsten carbide pin brazed into the body for superior wear resistance on hard surfaces like blacktop.
Installation: Quick and easy to apply; requires a 17/64" (6.8mm) hole to be drilled into the horseshoe before being driven in with a soft-face hammer.
Durability: These studs are designed to be long-lasting and can often be reused on resets by punching them out of the old shoe.
