Grade 2 Zinc Plated Steel Hex Bolt, 3/8"-16, 1-1/2" Length (Pack of 100)

Hex bolts have a chamfered point to aid insertion into a tapped hole or nut. Length is measured from under the head.Grade 2 fasteners are typically made of low-carbon steel and are commonly used for wood and general hardware applications where higher strength is not required. They have no radial markings on the head. Steels are designated by a 4 number SAE Steel grade.  The first two digits indicate the primary materials used to form the steel.  The last 2 digits identify the percentage of carbon for the alloy (in hundredths).  The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch).  Zinc Plating helps to prevent corrosion.Hex head fasteners can be driven with simple wrenches, and require minimal clearance above the fastener because they can be driven or loosened from the side.A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.

• Hex Bolts feature a chamfered point
• Zinc Plated Steel fasteners are suitable where strength and corrosion resistance are primary considerations
• Hex head for easy driving
• Length is measured from under the head
• Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
