Exclusive Whittet Higgins Bms-10 Bearhug Retaining Nut Stainless New Style [ScWM4HNu]

This series of BEARHUG Locknuts with a compression collar is fully interchangeable with the metric locknut made in accordance with ISO standard 2982 and usually identified with the KM prefix. All measurements are in millimeters.

This quality series of BEARHUG is manufactured with quality threads of tolerance grade and position 4H. This is more comparable to the Class 3 thread of the current American retaining nuts, which the usual 5H tolerance grade and position of the threads for bearing retaining nuts does not uniformly reach. The 5H is more comparable to Class 2.
