H4L 3/8 X 2 5/8 SS302HQ - 102053143

1. Nelson punching shear resistor studs (PSRS) are specifically designed to be stud welded to a flat steel rail to provide a strong, ductile reinforcing system to prevent punching shear where columns punch through concrete cast in place, floor, and foundation slabs. These are provided in 3/8", 1/2", 5/8" and 3/4" diameters and lengths up to 12" 2. Nelson headed concrete anchors (H4L) are designed to be welded to a variety of structural steel shapes. For welding into the fillet or onto the heel of an angle it is important that the studs are long enough to provide adequate anchorage length for concrete. 3. Nelson shear connectors (S3L) are typically used in composite steel construction for holding concrete slabs to steel members to resist shear forces and increase shear loading capacity in steel buildings, bridges, columns caissons, containment liners, etc. They also act as embedment anchors on miscellaneous embedded plates, frames, angles, strip plates, attachments and connections. Options for Welding Through Metal Deck are available for 3/4” diameter and smaller.
