Fasteners
A fastener (US English) or fastening (UK English) is a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. Steel fasteners are usually made of stainless steel, carbon steel, or alloy steel. Other methods of joining materials, some of which may create permanent joints, include: crimping, welding, soldering, brazing, taping, gluing, cement, or the use of other adhesives. Force may also be used, such as with magnets, vacuum (like suction cups), or even friction (like sticky pads). Some types of woodworking joints make use of separate internal reinforcements, such as dowels or biscuits, which in a sense can be considered fasteners within the scope of the joint system, although on their own they are not general-purpose fasteners. Furniture supplied in flat-pack form often uses cam dowels locke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screws
A screw is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to the screw head, head. The most common uses of screws are to hold objects together and there are many forms for a variety of materials. Screws might be inserted into holes in assembled parts or a screw may form its own thread. The #Differentiation between bolt and screw, difference between a screw and a bolt is that the latter is designed to be tightened or released by torquing a Nut (hardware), nut. The screw head on one end has a slot or other feature that commonly requires a tool to transfer the twisting force. Common tools for driving screws include screwdrivers, wrenches, coins and hex keys. The head is usually larger than the body, which provides a ''bearing surface'' and keeps the screw from being driven deeper than its length; an exception being the ''set screw'' (aka grub screw). The cylindrical portion of the screw from the underside of the head t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bread Clip
A bread clip is a device that is used to hold plastic bags closed, such as those in which sliced bread is commonly packaged. They are also commonly called bread tags, bread tabs, bread ties, bread buckles, bread-bag clips, or occlupanids. By sealing a bag more securely than tying or folding over its open end, and thus providing a nearly hermetic seal, the contents are preserved longer. Designs Simple Most designs of bread clip consist of a single plastic part through which the neck of a plastic bag can be threaded. Because these clips are cheap, ubiquitous, and come in a variety of shapes and colors, some people collect them. Most bread clips are made from plastic #6 polystyrene (PS), but Quebec-based bread clip manufacturing company KLR Systems released recyclable, cardboard bread clips in 2019, which they later switched to producing in 2022. Such clips are also used for Milk bag, bagged milk. In the Provinces and territories of Canada, Canadian provinces of Ontario, Quebec, ...
