Overview
This Grade 8.8 carbon steel hex bolt is engineered for demanding fastening applications in construction, machinery assembly, and general fabrication. It provides a robust and dependable connection where high tensile and shear strength are required. The black oxide finish delivers a uniform, dark appearance along with a layer of protection against rust and corrosion in non-severe environments. Supplied in a convenient bulk pack of 100 pieces, this fastener is ideal for high-volume projects, maintenance kits, and industrial inventory.
Key Features
Manufactured from medium carbon steel for a high strength-to-weight ratio Heat-treated to achieve a Grade 8.8 mechanical property rating Black oxide surface finish for basic corrosion resistance and a low-glare aesthetic Partial thread (non-threaded shank) design maximizes strength under shear loads Coarse thread pitch ensures faster installation and reduced cross-threading risk Standard hex head allows for secure wrenching with common tools Bulk packaging of 100 units supports cost-effective procurement and job site efficiency
