1/4-20 x 3/8" Slotted Pan Head Machine Screws Stainless Steel 18-8 Qty 100

Pan heads are slightly rounded with short vertical sides. Machine screws have machine threads for use with a nut or in a tapped hole. Machine screws are often used with nuts but also often driven into tapped holes (without nuts). They might be considered a screw or a bolt based on the Machinery's Handbook distinction. In practice, they tend to be mostly available in smaller sizes and the smaller sizes are referred to as screws or less ambiguously as machine screws, although some kinds of machine screw can be referred to as stove bolts. Holds object to another object that has a pre-threaded hole, frequently a nut. Usually manufactured from metal. Can be rotated into or out of the object using a screwdriver or wrench.

Key Notes:

Machine screws are uniformly threaded screws of 1/4" nominal diameter or less that is designed to be threaded into uniformly threaded nuts or threaded holes in the parts they are intended to fasten. Machine screws primary tightening is accomplished by turning the head of the screw. With a bolt, the primary tightening procedure might be accomplished by turning the nut.

Pan heads have a domed top with a flat load bearing surface on the underside that will hold materials being fastened firmly together.

The slot screw drive has a single slot in the fastener head and is driven by a flat-bladed screwdriver or common blade object. This drive is the best choice for the future maintenance of a project that could be potentially covered with paint or other coatings giving an easy option to clear the slot to unfasten

The vast majority of stainless steel fasteners are produced with metals from the austenitic family. Their high levels of chromium and nickel provide tough corrosion resistance and the ability to withstand considerable physical strain without fracturing, albeit at a higher cost than the martensitic varieties.

Made of stainless steel grade 18-8 which offers a high level of chemical and corrosion resistance and strength that will out perform and out last all zinc plated fasteners for years with out the need to perform costly and time consuming maintenance.
