Sae J429 Grade 8 normal specification for in-series metal screws screws, studs, SEMS screws along with ubolts in measurements upto 1-1/2 inch. It is typically constructed out of versions of moderate carbon dioxide. It have been made, fabricated and tested to follow the expectations determined by SAE J429 for evidence loading, yield and tensile strength, elongation, area roughness and heart hardness. Grade 8 Self Tapping Screws are one of the most commonly used industrial fasteners. It is one of the earliest engineered products of fastener. It is manufactured out of hardened steel, and their use powered the Industrial Revolution. And still it is incredibly common today; self-tapping screws include many styles and types which are made for specific fastening functions. Since they are used so heavily in the sheet metal trade, it can accurately be described simply a tapping screw, but is also regularly referred to as a sheet metal screw.

 

Grade 8 Hex Bolts is a type of threaded bolt which is characterized by their six-sided hexagonal-shaped head. It is suitable for use in a wide range of applications, typically construction and machinery. Grade 8 Metric Bolts are threaded fasteners whose length, thread pitch, thread length and thread length are offered in metric measurement, such as one millimeter. It can be fully or partially threaded; a partially threaded bolt has an area beneath the head that is bare from threads. Grade 8 Threaded Rod is a rod of varying length that is threaded in a helical structure and is often referred to as a stud. It is a relatively long rod that is threaded on both the ends; the thread can be extended along the complete length of the rod. It is been manufactured to be used in tension. 

 

Grade 8 Lag Screws is one of the toughest fasteners. It is an extremely sturdy fastener which is usually used to connect heavy lumber or other heavy materials that are bearing an intense load. It differs from normal wood, self-drilling or sheet metal screws. Grade 8 Plow Bolts are a specialized type of fastener. It is similar to carriage bolts, but the head of a plow bolt is concave or flat. It is used for creating mechanical bearings, which requires a smooth surface where the bolt heads can be efficiently pop out.  Grade 8 U Bolt is often used for the attaching of pipes or steel round bars to round wood or steel posts. It is an industrial fastener in the shape of the letter U with two threaded arms (or legs) extending from a curved base.
