In the case of hull breaches, these tools fastened steel plates over damaged areas. [3] These tools were developed by Mine Safety Appliances , for the United States Navy. [ 4 ] Powder-actuated tools were investigated and used prior to this development; they were used in anti-submarine warfare during the First World War and were the subject of a ...
A larger number indicates a longer nail, shown in the table below. Diameter of the nail also varies based on penny size, depending on nail type. Nails under 1 + 1 ⁄ 4 inch, often called brads, are sold mostly in small packages with only a length designation or with length and wire gauge designations; for example, 1″ 18 ga. or 3 ⁄ 4 ″ 16 ga.
Nails went from being rare and precious to being a cheap mass-produced commodity. Today almost all nails are manufactured from wire, but the term "wire nail" has come to refer to smaller nails, often available in a wider, more precise range of gauges than is typical for larger common and finish nails.
A pin nailer is a type of nail gun that drives simple pin-like fasteners as substitutes for finish nails. Pin nailers are often used on molding for furniture, cabinets, and interior millwork .

Type 304—the most common grade; the classic 18/8 (18% chromium, 8% nickel) stainless steel. Outside of the US it is commonly known as "A2 stainless steel", in accordance with ISO 3506 (not to be confused with A2 tool steel). [6] The Japanese equivalent grade of this material is SUS304.
Several modifications and shapes were introduced subsequently for various bones such as V-nails for tibia, radius [5] and ulna nails, Rusch nails etc. Although stainless steel was used for older IM nails, titanium has several advantages, including lower mechanical failure rates and improved biocompatibility .

A #7 finish is produced by polishing with a 280–320 grit belt or wheel and sisal buffing with a cut and color compound. This is a semi-bright finish that will still have some polishing lines but they will be very dull. Carbon steel and iron are commonly polished to a #7 finish before chrome plating.
Date nails are also found on utility poles, sometimes in conjunction with a nail showing the height of the pole in feet. The types of nails may have distinguishing characteristics, such as the date nail having raised digits and the "height nail" having incised digits. The pole height will be a multiple of five (e.g., "35" or "40"). [5]
