Dome-Head Hammer Drive Pin Anchor, 1-3/4" L x 1/4" Dia., 10 PK

Hammer-drive anchors and pins are engineered to set flush in recessed washers to help prevent tampering and removal. They are also designed to resist vibration, and will work in all poured concrete and brick materials. Unlike other security type anchors, they do not require special tools or welding to sit securely. The nut features a reversible design, making it compatible with flat head and round head applications. Use to secure prison furniture, burglar bars, security door frames, motion detectors, fencing, lock boxes, money meters, vending machines, benches, light fixtures, playground equipment, thresholds, stadium seating, cash machines, and mailboxes.
