Product Description

Hillman Anti-Turn Washers/Lag Drivers, 1/2in, 25 Pack, Gray

ANTI-TURN WASHERS FOR SECURE FASTENING: 1/2 in. galvanized anti-turn washers prevent bolts and fasteners from rotating during installation. Specialized design improves stability in fastening systems where unwanted movement can loosen hardware.
EXTENDED BARB DESIGN GRIPS AND PREVENTS ROTATION: Anti-turn barbs bite into soft materials when tightened, anchoring the washer in place and reducing rotation for improved reliability and stability in the fastening connection.
IDEAL FOR SOFT WOOD, PLASTIC, AND LIGHT METAL APPLICATIONS: Barbed design embeds into soft woods, plastics, and light metals to create a more secure, movement-resistant hold in fastening applications requiring extra stability.
MECHANICALLY GALVANIZED COATING MEETS ASTM A153: Galvanized coating provides strong rust and corrosion resistance conforming to ASTM A153 standards, making these washers suitable for outdoor and moisture-prone environments. 25-piece pack.
TRUSTED HILLMAN FASTENING SOLUTIONS: Hillman hardware products are engineered for consistent quality, dependable performance, and reliable fastening across construction, repair, and home improvement project applications.

The anti-turn washer has serrations that extend radially inward and/or outward to bite into the bearing surface. This type of washer is effective as a lock washer when used with a soft substrate, such as aluminum or plastic.
