FAQ:

Q: What is a domed head on a cap lock nut?

A: A nylon insert on these metric nuts prevents vibration from loosening them, and a domed head protects the threads at the end of the bolt from damage and debris. An irregularly shaped thread grips the bolt for a stronger hold than nylon-insert cap locknuts.

Q: What is the difference between aluminum cap nuts and steel cap nuts?

A: One- third the weight of steel, aluminum cap nuts resist corrosion in wet environments. Low- profile cap nuts are about 20% shorter than standard cap nuts for use in low-profile applications.

Q: What are EHEDG cap nuts?

A: Certified by EHEDG (European Hygienic Engineering and Design Group) to meet sanitary design standards, these cap nuts fit into tight spaces to cover and seal exposed threads in your food processing facility. Known for their strength, these steel cap nuts have a black-oxide finish to resist corrosion in dry environments.

Q: What are cap nuts used for?

A: The dome is open so these cap nuts can be used on bolts of any length. Cap nuts cover and protect threads while providing a finished appearance. Cover battery terminals to protect against corrosion and short circuits.
