1/2-13 UNC Stainless Steel Thin Hex Nuts Hexagon Jam Nuts, 304 Stainless Steel 18-8, Full Thread, Coarse Thread, 20 PCS

SIZE:1/2-13 Packaged Included: 20 PCS About The Jam Hexagon Nuts Nuts are widely used in conjunction with a mating bolt to fasten two or more parts together. The two parts are combined by their threads' friction, a slight stretching of the bolt and compression of the parts to be held together. In common use, a nut-and bolt joint holds together because the bolt is under a constant tensile stress called the preload. Jam hex nuts are thinner than normal standard hex nuts for use in tight areas and widely used with another jam nut to help prevent loosening. The high quality 304 stainless steel provide perfect strength and good corrosion resistance in bad environments like high temperature, cold weather and high humidity areas without the need for time consuming and costly maintenance.
