Construction Specs

Shear Connector Stud
SHEAR CONNECTOR STUDS are designed to effectively tie the concrete to the steel beams and to resist shear loadings between the concrete slab and steel beam in composite construction. All orders for studs include required ferrules.

LENGTH: Length is before weld. Studs when welded to base metal will be approximately 3/16" shorter after weld and when welded thru-deck 3/8" shorter after weld. Lengths for shear connector studs are generally set by governing specifications. Consult your Perry representative for other lengths available for specific applications.

MATERIAL: Low carbon steel, ASTM A108, stainless steel (except Type 303).

Headed Anchor
HEADED ANCHOR STUDS are designed for welding in the fillet or to the heel of angles. When ordering specify if studs are to be welded to flat surfaces or in fillet or to heel of angle. AlI orders for studs include required ferrules.

LENGTH: Length is before weld. Stud diameters (D) 1/2" and below will be approximately 1/8" shorter after welding. 5/8" will be approximately 3/16" shorter after welding. Maximum length available for cold headed product is 8-3/16". Prices on hot formed studs over 8-3/16" available upon request.

  1. Type A studs shall be general purpose of any type and size used tor purposes other than shear transfer in composite beam design ana construction.
  2. Type B studs shall be studs that are heated, bent, or of other configuration in 1/2 in. (12.7mm), 5/8 in. (15.9 mm), 3/4 in. (19mm), 7/8 in (22.2 mm) and 1 in. (25 4 mm) diameter that are used as an essential component in composite beam design and construction.
  3. Type C studs are cold-welded deformed steel bars manufactured in accordance with specification ASTM A496 having a nominal diameter equivalent to the diameter at a plain wire having the same weight per toot as the deformed wire. ASTM A496 specifies a maximum diameter of 0.628 in. (16 mm) maximum. Any bar supplied above Wat diameter must have the same physical characteristics regarding deformations as required by ASTM A496.
