Hex Head Partial Thread Bolt, Galvanized Long Half Thread Hex Screw

Product Introduction

Hex head partial thread bolt is one of the most general structural fastening parts. Manufactured by one-step cold forging technology, the bolt body has stable mechanical performance, good tensile strength and strong load-bearing capacity. The unique half-thread structure leaves a smooth shank section in the middle of the bolt. When fastening thick plates, the smooth rod can pass through the workpiece without damaging the thread, and the threaded section cooperates with the nut to complete locking, effectively avoiding thread wear and sliding caused by full-thread bolts. Standard hexagonal head design is compatible with open-end wrenches, socket wrenches and electric tools, greatly improving installation efficiency. Electro-galvanized protective layer isolates air and moisture, effectively slowing down oxidation and rusting, adapting to indoor and conventional outdoor working environments.

Product Advantages

1. Half Thread & Smooth Shank Design: Protect threads during thick plate installation, reduce wear and sliding risk.

2. Standard Hex Head: Compatible with all common wrench tools, convenient for manual and automatic assembly.

3. Galvanized Anti-Corrosion Surface: Excellent rust resistance, extend service life of connection joints.

4. High-Strength Carbon Steel Raw Material: Stable mechanical property, not easy to bend or deform under heavy load.

5. Flexible Customization: Custom bolt diameter, total length, thread length and head size per customer drawings.
