Midwest Fastener 00338 Hex Head Bolt, 1/2-13 x 2 inches

Midwest Fastener 00338, SKU 4511523, is a set of 50 hex head bolts designed for the secure mechanical joining of two or more parts via a threaded hole or nut. Each bolt is 1/2-13 inches in size and 2 inches in length, with coarse threads and a hex drive for use with a standard wrench or socket.

Construction and Key Features

The bolts are made of alloy steel and have a zinc coating. This coating helps protect against rust and makes them suitable for use in indoor spaces or in protected outdoor locations in a moderately harsh environment. Grade 5 indicates high strength and, according to available data, corresponds to a minimum tensile strength of 120,000 psi, making them a good choice for general applications where a balance between strength and practicality is sought.

The thread is full from tip to head, and the coarse profile facilitates faster installation and ensures a secure hold under load. The hex head allows for easy tightening and removal with commonly available tools.

Application

These bolts are used for fastening in construction, including the joining of structural elements such as frames and beams. They are also suitable for automotive repairs, for example, for mounting engine components, suspension and chassis parts, as well as for machine maintenance where housings, brackets, and clamps are secured.

The 1/2-13 size and 2-inch length make them a practical choice for standard imperial fastening applications. According to the provided information, the bolts are installed by aligning them with a threaded hole or nut and tightening them with a suitable hex tool to the required torque. It is noted that the typical dry-fit torque range for 1/2-13 Grade 5 is approximately 75-90 ft-lbs, depending on lubrication and applicable standards.
