PS
Punching Shear Resistor
COX INDUSTRIES PSR STUDS are designed for welding to flat strip steel to reduce punching shear stress. When ordering specify overall height of rails and diameter of stud. All orders for studs include required ferrules.
MATERIAL
- Low carbon steel, ASTM A29/A108, 1010-1020
LENGTH
- Length is before weld. Stud diameters 1/2" and below will be approximately 1/8" shorter after welding and studs 5/8" and larger will be approximately 3/16" shorter after welding. Maximum length available for cold headed product is 10-7/8". Prices on hot formed studs over 10-3/16" available upon request.
FLUX
- COX INDUSTRIES PSR Studs are solid fluxed.
