Hogue grip screws are manufactured from heat treated 416 stainless steel which is much tougher and resistant to damage than conventional screws. Most standard screws twist off or strip out at a much lower torque. Hogue grip screws are custom machined specialty screws available in either slotted or Allen (hex). Make no mistake, our grip screws are the finest, most durable grip screws available.
Screws have 4mm x .7mm threads. They will not fit early Sig models with smaller threads.
