3M™ E-A-R™ Skull Screws™ Earplugs P1300, Uncorded

The 3M™ E-A-R™ Skull Screws™ Earplugs bring rugged style and high NRR* Rating for those high noise exposed workers. Though they look like threaded metal, they're made with soft foam to help protect the wearer. Made with stem grips that looks like a philips head screw, this push-to-fit earplug doesn't require rolling down of the earplug which can help keep the foam tips clean and clear of debris, dirt, and other foreign matter when inserting with gloves or dirty hands. E-A-Rfit™ provides an accurate quantitative assessment of how much noise reduction a hearing protector provides to an individual worker. Ideal applications: Assembly, Blasting, Cleaning, Demolition, Electrical, Facility Maintenance, Grinding, Machine Operations, Painting, Sanding, Welding, and more. (120 earplugs per box) Show Less
