Collar Studs

COX INDUSTRIES CS COLLAR STUDS are designed for fastening applications to provide a spacer between the parent metal and the part secured on threaded extension. They are available in diameters 1/4″ through 1/2″.

All orders for studs include required ferrules.

MATERIALS

Low carbon steel ASTM A29/A108 Grades 1010-1020. Weldable stainless steels are available (except Type 303) with Type 302 being the most common.

LENGTH

Studs can be produced in any length above the standard minimum (L). Length is listed before weld. Stud diameters 1/2" and below will be approximately 1/8" shorter after welding.

THREAD

Standard thread is UNC-2A for imperial threads and 6g for metric threads.

PLATING

Plating is used to increase a stud's corrosion resistance. Unless specified at time of order, all Cox studs will be supplied plain. Plating options include copper, nickel, zinc and zinc dichromat.

ANNEALING

Upon request, stud ductility can be increased by annealing to 75 Rockwell B for low carbon steel and 90 Rockwell B for stainless steel.

FERRULES

All orders for studs include required ferrules for welding. Please specify when ordering what type of ferrule is required for your application.

FLUX

Standard collar studs are solid fluxed.
