Superior Strength for Demanding Applications
When the structural integrity and safety of your heavy-duty equipment are on the line, every single component matters. The Buyers Products 1/4″-20 x 1″ Grade 5 Hex Head Cap Screw (FCS025020100) is engineered to provide the superior strength and exceptional holding power required for the most demanding applications. This is not just a standard screw; it’s a critical fastener designed for ultimate durability, ensuring that your assemblies remain secure and steadfast under constant stress, heavy loads, and intense vibration. Trust this essential piece of hardware to maintain the reliability of your valuable machinery, from commercial trucks to agricultural equipment.
Engineered from High-Performance Grade 5 Steel
Crafted from premium medium carbon steel that has been expertly quenched and tempered, this cap screw meets and exceeds the stringent requirements of SAE J429 Grade 5 specifications. This critical heat-treatment process significantly increases its tensile strength to a minimum of 120,000 PSI, making it substantially stronger and more resilient than common Grade 2 or un-graded hardware found in retail stores. This enhanced strength provides excellent resistance against shearing forces and ensures a secure, high-tension clamp load, preventing loosening in the high-vibration environments common to the trucking, construction, and agricultural industries. Whether you are assembling a new piece of equipment or performing a critical field repair, you can rely on the robust performance of a genuine fastener from Buyers Products.
Designed for Versatility and Ease of Use
The FCS025020100 features a standard hexagonal head, precision-formed for a perfect fit with common wrenches and socket sets, allowing for accurate and high-torque application without stripping. Its 1/4″-20 coarse thread pitch (UNC) is the industry standard for general-purpose fastening, offering an ideal balance between rapid installation and strong, reliable thread engagement that resists stripping and cross-threading. With a 1-inch length (measured from under the head), this screw is perfectly sized for a vast array of applications, including securing mounting plates, assembling vehicle frames, attaching accessories to snowplows and salt spreaders, and general machinery fabrication. Its versatility makes it an indispensable part of any professional workshop or maintenance inventory, and a staple in our Uncategorized hardware collection.
