Value Collection HN4XX04500 Hex Nut M45 X 4.5 Din 934

Product Description

The VALUE COLLECTION HN4XX04500 is a heavy-duty metric hex nut designed for high-load fastening applications requiring corrosion resistance. Manufactured from Grade 316 Austenitic Grade A4 stainless steel with a bright, uncoated finish, this nut meets DIN 934 standards. It features a right-hand thread in M45 x 4.5 sizing with a 6H thread fit class, 70 mm width across flats, and a 36 mm height. It is suited for industrial, marine, chemical, and structural applications where stainless fasteners are specified by engineers, millwrights, or maintenance technicians working with large-diameter metric fastening systems.

This hex nut is used in applications requiring metric fasteners with a large thread diameter and pitch. Typical install scenarios include heavy equipment assembly, marine hardware, processing plant piping flanges, and structural steel connections where Grade 316 stainless steel is specified for its chloride and corrosion resistance. The DIN 934 standard makes it compatible with metric bolt and stud installations requiring a standard-profile hex nut with a 6H thread tolerance class.

Key Features

• Grade 316 Austenitic Grade A4 stainless steel construction for superior corrosion resistance
• M45 x 4.5 right-hand metric thread, DIN 934 standard
• 6H thread fit class for standard metric thread tolerance
• 70 mm width across flats for use with large-drive tooling
• 36 mm height provides full engagement depth on large-diameter fasteners
• Bright, uncoated finish — no secondary processing required

Compatibility

Designed as an OEM-style replacement or new-installation hex nut for metric bolts and studs conforming to DIN 934 with M45 x 4.5 thread specifications and a 6H thread fit class.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or structural tradespeople using appropriate metric wrenches or impact tooling sized for a 70 mm across-flats profile. Always confirm mating bolt grade and thread class compatibility before installation. Fastener assemblies in structural or pressure-bearing applications should be torqued per the applicable engineering specification or relevant industry standard. Do not mix stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion without appropriate isolation.
