The Unbrako 116113 1-1/2" x 6" Hex Socket Head Cap Screw is a high-quality fastener designed for demanding industrial applications. Manufactured by Unbrako, a leader in high-tensile industrial fasteners since 1911, this socket head cap screw offers exceptional strength and reliability. Constructed from alloy steel, the 116113 screw provides superior tensile strength, significantly surpassing standard low-carbon steel fasteners. This enhanced strength ensures the screw can withstand higher loads and stresses, reducing the risk of failure in critical applications. The hex socket drive design allows for efficient torque application, minimizing the risk of stripping and ensuring a secure fit. This feature is particularly beneficial in environments where precision and reliability are paramount. Unbrako's commitment to quality is evident in the 116113 screw's design, which includes a compound fillet radius that doubles the fatigue life at the critical head-shank juncture. Additionally, the radiused root runout (3R) provides a smooth form that distributes stress, increasing the fatigue life of the thread run-out by up to 300% in certain sizes. The 116113 screw is uncoated, offering versatility for various applications where coating is not required. Its dimensions1-1/2" diameter and 6" length make it suitable for a wide range of industrial uses, including machinery assembly, structural applications, and equipment maintenance. By choosing the Unbrako 116113 Hex Socket Head Cap Screw, you are investing in a high-performance fastener that delivers enhanced strength, durability, and reliability, thereby improving the operational efficiency and safety of your equipment.
