Brevet d'invention n° 176 400 du 29 mai 1886. These first versions had an S-shaped spring in the "male" disc instead of a groove. Australian inventor Myra Juliet Farrell is also credited with inventing a "stitchless press stud" and the "stitchless hook and eye". In America, Jack Weil (1901–2008) put snaps on his iconic Western shirts, which spread the fashion for them.

Myra Juliet Farrell (also Myra Juliet Welsh and Myra Juliet Taylor; 25 February 1878 – 8 March 1957) was an Australian visionary, inventor and artist. Born in County Clare, Ireland, she migrated to Australia as a child, growing up in Broken Hill, travelled widely and settled in Mosman, Sydney. She held more than two dozen patents ranging from a military barricade to a press stud that could be applied without stitching.

According to the author Ruth Park, this device promoted the comment from Americans that Australian mothers had learnt from kangaroos to carry their babies in pouches. Inventions for rural industry included an automated fruit picker and packer, and a device for sampling and weighing wheat. Farrell also invented the press-stud that can be attached to a garment without stitching, and the folding pram hood. By 1915 Farrell had 24 patented inventions.

It was by observing the special armholes of T-shirts worn by American soldiers, who could put on their underwear without taking off their helmets, that Petit Bateau invented its first baby bodysuits in 1950, designed for ease and practicality. The Valton family devised a new way of putting on children's clothes: over the head, thanks to a more oval neckline. In 1980 the Valton family continued to revisit the traditional bodysuit for babies by creating the first model with press stud closure between the legs to further facilitate the dressing and movement of toddlers.

There is also variation in the number of magazines a pouch holds. The norm is for two magazines to be carried, but there are also variants which allow for carriage of more, or less, dependent on the needs of the officer. Also, similar to holders of other items of equipment, these can be found with either an open top design, or a closed design fastened either with a press stud or velcro. Other pouches hold a single magazine but are attached to the front of the officer's firearm holster.

Prior to the lug's invention plug bayonets were used, which were stuffed into the muzzle's end from a tight-fitting stub, rendering the firearm virtually useless and certainly preventing it from being discharged. But by the late 17th century, this type of bayonet was entirely phased out and subsequently replaced with the socket bayonet, that slides over the muzzle with the blade offset to the side, just above or underneath. The socket bayonet would be replaced by the press stud and bayonet lug. Bayonet lugs are usually located near the muzzle end of a musket, rifle, or other longarm barrel.

The PLCE webbing system is produced from double-layered 1000 Denier internally rubberised Cordura Nylon, a long lasting and hard wearing fabric. Olive webbing of the same material ("1000 D") is being incorporated, along with a variety of hard wearing plastic fasteners (ITW Nexus), Hook and loop fasteners (Velcro) and anti-magnetic press stud fasteners ("Pull the Dot"). The pouches are opened and closed with Spanish Tab fasteners, they can be closed in two different ways, quick release or secure. Small sections of Velcro, sewn on the inside of the lids of the pouches, and the top front section of the pouches, allow for easy and effortless fastening.

However, it was cut like the Denison smock, with smaller Newey press-stud (snap) fastened (but now bellowed) pockets, a full length zip without buttons down the front, the traditional olive green knitted wool cuffs, and a 'crotch flap' on the outside of the back. With the introduction of the British Army's latest multi-terrain camouflage pattern (MTP), a version of the "Smock, Parachutist" in that pattern was introduced as well and is currently on issue to members of the Parachute Regiment. The Canadian Airborne Regiment was first issued an olive green replacement for the Denison in the 1950s, and in 1975 a Disruptive Pattern parachute smock entered service, remaining in the inventory until the regiment disbanded in 1995.

The two halves of a riveted leather snap fastener. The top half has a groove which "snaps" in place when "pressed" into the bottom half A snap fastener (also called press stud, popper, snap or tich) is a pair of interlocking discs, made out of a metal or plastic, commonly used in place of traditional buttons to fasten clothing and for similar purposes. A circular lip under one disc fits into a groove on the top of the other, holding them fast until a certain amount of force is applied. Different types of snaps can be attached to fabric or leather by riveting with a punch and die set specific to the type of rivet snaps used (striking the punch with a hammer to splay the tail), sewing, or plying with special snap pliers.

Where higher voltages are present, extra resistance (0.75 megohm per 250 V) is added in the path to ground to protect the wearer from excessive currents; this typically takes the form of a 4 megohm resistor in the coiled cable (or, more commonly, a 2 megohm resistor at each end). Wrist straps designed for industrial use usually connect to earth bonding points, ground connections built into the workplace, via either a standard 4 mm plug or 10 mm press stud, whereas straps designed for consumer use often have a crocodile clip for the ground connection. In addition to wrist straps, ankle and heel straps are used in industry to bleed away accumulated charge from a body. These devices are usually not tethered to earth ground, but instead incorporate high resistance in their construction, and work by dissipating electrical charge to special floor tiles.
