- Enhanced load distribution and surface protection from the wide, rounded head, minimizing surface damage and providing a larger bearing area.
- Reliable corrosion resistance provided by the zinc-plated steel construction, extending service life in various industrial environments.
- High tensile strength of 60,000 PSI (Grade 2) ensures dependable performance for medium-duty fastening requirements.
- Consistent and easy installation with UNC coarse threading and Class 2A fit, allowing for quick assembly and disassembly.
- Proven material durability with a Rockwell B69 hardness, offering excellent resistance to wear and deformation.
- Broad compatibility and secure fit in pre-drilled holes due to the specific neck diameter and length.
Professional Applications & Engineering Value
This 1/4"-20 Carriage Bolt is engineered to solve common industrial challenges like joint loosening and material degradation. The zinc-plated steel construction provides a protective barrier against rust, crucial for outdoor equipment, agricultural machinery, and structural assemblies exposed to the elements. The knurled neck is a critical feature that bites into the mating material, providing exceptional anti-rotation security to maintain clamp load in high-vibration environments such as automotive chassis, trailer beds, and wooden structures. The UNC coarse thread and Class 2A fit ensure rapid installation and reliable performance, making it a go-to solution for maintenance, repair, and operations (MRO) where efficiency and durability are paramount.
Specification Summary & Compliance
This carriage bolt adheres to precise dimensional standards, including a Class 2A thread fit for consistent assembly. It is manufactured to meet ASTM A307 and SAE J429 specifications for Grade 2 fasteners. The product is fully compliant with environmental and safety regulations, including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006).
