Round Heads have a tall domed top and a flat bearing surface. 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.

• 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.
• Round heads feature a round top very similar to half of a sphere 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
• Fastenere brass fasteners are cleaned and applied with a sealer that brings out the bright yellow brass finish and helps to maintain it.
• Made of Grade 360 Brass, known for its strength and resistance to corrosion with properties closely resembling that of steel and offering the highest machinability of all copper alloys.
