Eclipse Magnetics N35 Neodymium Ring Magnets with Countersunk Hole are compact, high-strength rare-earth magnets designed for secure screw mounting and reliable magnetic holding.
Manufactured from N35 grade Neodymium (NdFeB), each magnet features a central countersunk hole so the fixing screw can sit neatly within the magnet profile. This makes the range well suited to mounting, fixing, closure and assembly applications where a clean installation is required.
Five variants are available, ranging from 15.4mm to 37mm in outside diameter, with M3, M4 and M6 screw head sizes. Pull forces range from 3.5kg up to 8.1kg depending on the selected model.
The nickel-plated finish provides surface protection and durability, while the compact ring format makes these magnets suitable for engineering assemblies, fixtures, furniture, signage and general magnetic fixing applications.
The range is suitable for operating temperatures up to 80°C.
