Square-Head Bolt Overview
Features: Square-head bolts are prevalent in railway tracks, characterized by their square-shaped heads and availability in various sizes. Typically crafted from high-strength steel, these bolts are engineered to endure substantial loads and high stress levels.
Advantages
Strength and Durability: Square-head bolts exhibit a high strength-to-weight ratio, enabling them to withstand heavy loads and elevated stress levels.
Ease of Installation: These bolts are easy to install, and their square heads can be quickly tightened using a wrench.
Disadvantages
Potential for Loosening: Due to factors such as vibration and thermal expansion, square-head bolts may become loose over time, impacting their effectiveness.
Corrosion Concerns: Despite being hot-dipped galvanized for corrosion protection, square-head bolts can still corrode over time, potentially leading to rail joint failure.
