Full Thread Hex Head Bolt
This full thread hex bolt is a universal economical fastener designed for thin plate and multi-layer component assembly.
Manufactured from Grade 4.8 carbon steel with blue white zinc electroplating finish, it forms a compact rust-proof protective film to resist oxidation under indoor and slightly humid outdoor conditions. The full rolling thread extends across the whole bolt shank, enabling free adjustment of fastening position when assembling thin stacked workpieces, which brings higher flexibility compared to half-thread bolts with fixed smooth shank.
The regular hexagonal head fits open-end wrenches, box wrenches and socket spanners perfectly, supporting stable, slip-free tightening operations. Standard pitch rolling thread delivers smooth cooperation with hex nuts, flat washers and spring washers to maintain long-term reliable clamping force.
With balanced tensile and shear performance and low comprehensive cost, it is widely adopted for general industrial assembly projects. All finished bolts pass hardness, tensile strength and thread precision tests before shipment, complying with international general fastening standards. Custom ultra-long thread lengths and alternative surface coatings can be produced to satisfy bulk order requirements.
