1/4 x 3-1/4" Wedge Type Stud Bolt Anchor, Steel, 25/Pack

To install, simply drill a hole of the proper diameter in concrete, ensuring it exceeds the minimum recommended depth. Drive the Wedge Anchor through your fixture until the nut sits flush. Then, tighten the nut until you feel wrench resistance, typically three to four full turns past hand-tight. Secure and reliable, it's perfect for anchoring applications where strength and durability are essential.
