Product Technical Specifications
Enhance your project's stability with IMSCREWS Premium 1/2"-13 Hex Thickened Nuts. These heavy-duty fasteners are designed for high-stress applications where standard nuts might fail. Manufactured to GB6170 standards, the thickened profile (11.8mm height) ensures maximum thread contact and distribution of force, making them a top choice for critical structural connections.

Exceptional Durability for Any Environment
Made from 304 Stainless Steel, these nuts are engineered for longevity. Whether you are building an outdoor deck, repairing a garden fence, or working on a freshwater marine project, the corrosion-resistant properties of 304 stainless steel provide peace of mind against rust and weathering. Please note that while 304 stainless steel is generally non-magnetic, it may develop a slight magnetic pull during the manufacturing and cold-forming process; this does not affect its performance or material integrity.

Installation & Tool Compatibility
For a secure and professional fit, these nuts feature a 21.7mm width across flats. We recommend using a 7/8 inch or 22mm wrench/socket for installation. The 1/2"-13 UNC (Unified Coarse) thread ensures easy starting and rapid assembly when paired with matching bolts.

Common Applications & FAQ
Can it be used outdoors? Yes, the 304 stainless steel construction is specifically chosen for outdoor and humid environment reliability.
Is this nut heat resistant? 304 stainless steel maintains its strength at high temperatures, with a recommended continuous service temperature up to approximately 800¡ãF (425¡ãC).
Can it be used for automotive repairs? Absolutely. Their heavy-duty nature makes them suitable for non-critical automotive bodywork, frame attachments, and trailers where 1/2 inch bolts are required.
What is in the box? This package contains 5 pieces of 1/2"-13 Hex Thickened Nuts (Tools and additional accessories not included).
