Plain 300 Stainless Steel Large Panel Screws, 1/4" - 20, 5/8 inches Head Diameter, 1 inches Length (Pack of 1)

Panel screws are thumb screws that attach to panels with a retaining washer (not included), staying in place even when not tightened. They have an easy-grip head that allows for simple “by-hand” installation, just like conventional thumb screws. The large panel screw has an extra large head with a straight knurled surface for additional grip for manual adjustment.

Plain stainless steel 300 provides better corrosion resistance than steel, making it ideal for a range of environments. Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their wide use in practically every industry. The panel screw has a one-piece construction for strength.

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.
