Push-to-fit design ensures earplugs stay clean, even when hands or gloves are dirty
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.
Compatible with the 3M™ E-A-Rfit™ Dual-Ear Validation System
E-A-Rfit™ provides an accurate quantitative assessment of how much noise reduction a hearing protector provides to an individual worker.
How to use
Fitting Instructions
1. INSERT rounded ear tip into ear canal WHILE PULLING ear outward & upward with opposite hand. ADJUST for greatest noise reduction.
2. CHECK FIT after inserting earplug
3. PULL earplug stem gently. Earplug should not come out of the ear easily. If it does, remove earplug & repeat fitting.
4. LISTEN to steady loud noise with earplugs in both ears. Cover ears with tightly cupped hands. Noise should sound about the same whether or not ears are covered.
5. WIPE earplugs with a clean cloth when dirty.
6. REPLACE if earplugs are damaged or when they are no longer soft and pliable.
CAUTION: For greater comfort and safety, remove earplug slowly with twisting motion to gradually break the seal.

- U.S. EPA specifies the NRR as the measure of hearing protector noise reduction. However, 3M makes no warranties as to the suitability of the NRR for this purpose.
- 3M strongly recommends personal fit testing of hearing protectors.
- Research suggests that users may receive less noise reduction than indicated by the attenuation label value(s) on the packaging due to variation in fit, fitting skill, and motivation of the user.
- Refer to applicable regulations or guidance on how to adjust attenuation label values.
- It is recommended that the NRR be reduced by 50% to better estimate typical protection.
