22x186 High Strength T-Bolt | DIN Standard T Head Bolt for Railway Construction & Fastening Project
Product Overview
Our 22x186 T-Bolt is a standard heavy-duty T head bolt specially produced in fixed size 22mm diameter and 186mm length. Made of premium high carbon steel with integral forging molding, this T-type bolt features precise thread, high tensile strength and strong shear resistance. Adopting professional heat treatment and surface anti-rust treatment, 22x186 T bolt fits perfectly with rail fastening system, steel structure connection and mechanical equipment fixing. Strictly manufactured according to industry standard, it provides stable, safe and long-lasting fastening performance for engineering projects.
Common Challenges
In railway track laying, steel structure installation and industrial equipment fastening, ordinary bolts often have obvious defects. Common hex bolts are easy to slip during installation, cannot be positioned quickly, and are not suitable for embedded groove installation. Unstandard size bolts lead to poor matching with rail accessories, easy loosening under long-term vibration, causing hidden safety hazards. Inferior raw material bolts are prone to bending, thread slipping and rust corrosion outdoors, increasing later maintenance cost and project downtime.
Our Solution
Our standardized 22x186 T-Bolt perfectly solves the above points. Special T-head design can be directly embedded in the reserved groove, realizing quick positioning and anti-slip installation without extra fixing tools. Fixed 22x186 standard size ensures 100% matching with conventional railway fasteners and structural accessories. High carbon steel forging + integral heat treatment greatly improves tensile and shear strength, resistant to vibration and heavy pressure. Multiple surface treatments such as black oxide and hot-dip galvanizing are optional, effectively anti-rust and anti-corrosion, adapting to outdoor, humid and harsh working environment, reducing replacement frequency and engineering maintenance cost.
The 22x186 T-Bolt adopts classic T-head structural design, the wide T-shaped head is stuck inside the preset mounting groove to limit rotation and displacement. The threaded rod body passes through the reserved hole of the connected component, matched with standard nut and washer for locking and pressing. After heat treatment, the bolt body maintains high overall toughness, evenly disperses pressure and vibration load during operation. The surface protective layer isolates air and moisture, avoiding oxidation rust, and keeps long-term stable fastening effect in continuous vibration and outdoor environment.
Selection Guide
Confirm Size: Choose fixed standard 22x186 T-Bolt directly for conventional rail and structural groove matching, no need to adjust size.
Strength Grade: 8.8 grade for conventional static load projects; 10.9 grade for heavy load, vibration frequent railway and bridge engineering.
Surface Treatment: Indoor dry environment choose black oxide; outdoor, coastal and rainy area choose hot dip galvanized for better anti-corrosion.
Matching Accessories: Use matched standard nut and flat washer together, to improve fastening tightness and anti-loosening effect.
