Sanitary Spade-Head Thumb Nuts

Cover and protect threads in sanitary environments, such as food-processing and pharmaceutical plants. These thumb nuts have smooth surfaces, rounded edges, and no holes or gaps where bacteria could grow. Twist the spade head to tighten them by hand, without the need for tools that could scratch equipment.

Profile

Standard Profile

Super-Corrosion-Resistant 316 Stainless Steel—Won't corrode from frequent washdowns and can stand up to the harshest cleaners and detergents.

Narrow Profile—Slimmer than standard-profile nuts to fit in tight spaces.

Standard Profile—The wide gripping area gives you more leverage than narrow-profile nuts, so you can apply more torque for a tighter fit.
