4-40 Flat Head Countersunk Machine Screws Slotted Drive Stainless Steel 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.

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 outperform and outlast all zinc plated fasteners for years without the need to perform costly and time consuming maintenance.
