The VALUE COLLECTION 556066PR is a metric hex nut in M30 x 3.50 thread size, manufactured from Class 8 steel with a zinc-plated finish. It measures 46 millimeters across flats and 24 millimeters in height, with a right-hand thread form conforming to DIN 934 and ISO 4032 standards. This nut is suited for high-load bolted assemblies where a standardized metric fastener is required. Maintenance technicians, millwrights, and mechanical contractors install this type of nut across industrial, commercial, and heavy equipment applications.
The 556066PR is appropriate for use in structural connections, machinery frames, flanged joints, and equipment mounting where M30 metric hardware is specified. Its Class 8 rating indicates it is compatible with medium-to-high-strength bolted connections. The zinc plating provides a baseline level of corrosion resistance suitable for indoor and sheltered outdoor installations. This nut follows DIN 934 and ISO 4032 dimensional standards, making it interchangeable with other hardware meeting those specifications.
Designed for use with M30 x 3.50 metric bolts and threaded rod conforming to DIN 934 and ISO 4032 standards. Suitable for structural and mechanical assemblies requiring Class 8 metric hex nuts.
Installation is performed by millwrights, maintenance mechanics, or licensed tradespeople using standard metric wrenches or sockets sized for a 46-millimeter across-flats dimension. De-energize and lock out any equipment before fastener service on powered machinery. Verify thread engagement length meets the requirements of the applicable structural or mechanical specification before final torque. Do not mix with inch-series hardware or fasteners of differing thread pitch.
