Bowmalloy BOW36609 Hex Nut 7/8-9 Grade 9 Steel

Product Description

The BOWMALLOY BOW36609 is a heavy-duty hex nut designed for high-load fastening applications where strength and corrosion resistance are critical. Manufactured from Grade 9 steel with a Bowma-Guard zinc-plated clear chromate finish, this nut delivers a Rockwell hardness rating of 26-36 HRC. It features a 7/8-9 thread size with right-hand threading and meets ANSI ASME B18.2.2 standards. Mechanical contractors, industrial maintenance technicians, and structural assembly professionals install this nut where elevated tensile strength is required over standard Grade 5 or Grade 8 fasteners.

This hex nut is suited for heavy industrial, structural, and mechanical assembly applications that demand high-strength fasteners. The 7/8-9 coarse thread profile is commonly specified in structural steel connections, heavy equipment assembly, and power transmission mounting. The zinc-plated clear chromate finish provides baseline corrosion protection appropriate for controlled environments and covered assemblies. Package quantity is 25 pieces per order.
