The Owlett-Jaton SAE Grade 5 UNC Hexagon Bolts are high-tensile fasteners engineered for demanding structural and mechanical projects where durability is non-negotiable. Designed for both professional contractors and serious DIY enthusiasts, these 1/2-13 UNC x 1.1/2 bolts provide reliable clamping force and easy installation; however, users should ensure they are using the correct thread pitch for their specific application as these bolts are strictly sized for UNC standards.

Grade 5 refers to the SAE (Society of Automotive Engineers) standard for high-tensile steel bolts, indicating a specific minimum yield and tensile strength.
Yes, Grade 5 bolts are commonly used in automotive applications, provided they meet the specific thread and length requirements for your vehicle's manual.
No. UNC (Unified National Coarse) is an imperial standard and will not thread into metric-sized nuts.
These bolts require a standard imperial wrench size compatible with a 1/2-inch bolt head, typically a 3/4-inch wrench or socket.
These bolts have a grey finish, but for high-exposure exterior environments, additional corrosion protection is recommended.
Generally, yes, as long as the threads are not deformed, stretched, or significantly rusted from their previous use.
Verify that both components are 1/2-13 UNC. If threads are damaged, attempt to clean them with a thread file or replace the component.
Ensure your wrench or socket is the correct size and fully seated on the hex head before applying high torque.
Clean the surface with a wire brush and apply a protective rust-inhibiting coating or paint to prevent further corrosion.
To install, select an appropriate wrench or socket size that matches the hex head. Ensure the threading of the bolt matches your mating component (1/2-13 UNC). Do not force the bolt if resistance is met during the initial threading, as this indicates a mismatch or debris in the hole. For long-term care, keep the threads clean and consider a light application of machine oil if the environment is prone to rust. Store in a dry location to maintain the integrity of the steel.
