Steel Hex Bolt, Grade 5, Zinc Plated Finish, Hex Head, External Hex Drive, Meets IFI 111/SAE J429, 1-1/4" Length, Fully Threaded, 5/16"-18 UNC Threads (Pack of 25)

The grade 5 steel hex bolt has a zinc plated finish and an external hex drive, and meets Industrial Fasteners Institute IFI 111 and Society of Automotive Engineers SAE J429 specifications. Grade 5 steel, composed of quenched and tempered medium carbon steel, is often used in applications where strength is the primary concern. The material is magnetic. The zinc plating offers corrosion resistance and a reflective appearance. The external hex drive has six flat sides that a wrench can grip to turn the screw from the side, enabling use when there is no space above the head for a driver.

Cap screws and hex bolts are threaded fasteners with thick hex-shaped heads that can be used with threaded nuts or in areas with limited clearance above the tapped (threaded) hole. Cap screws have slightly different dimensions than hex bolts and have a washer face underneath their unflanged hex head to act as a large bearing surface against the mating material.
