A machine screw is screwed into the sleeve, causing the anchor to bend, expand, spread and grip against the inside of the hole or behind it (in hollow contexts such as drywall over stud cavities, or hollow doors). [1] Mollies come in various diameters and grip lengths (shank lengths) for different drywall thicknesses and to support different ...
The screw itself should be drilled a minimum of 1" into the concrete to hold effectively and a maximum of 1-3/4" or the threads will wear and will lose holding power. Ideally 1-1/4" to 1-1/2" of screw thread in the concrete. [1] So for example, if a 1/2" board is being screwed onto the concrete, a 1-3/4" to 2" concrete screw should be used ...
Nails are made in a great variety of forms for specialized purposes. The most common is a wire nail. [2] Other types of nails include pins, tacks, brads, spikes, and cleats. Nails are typically driven into the workpiece by a hammer or nail gun. A nail holds materials together by friction in the axial direction and shear strength
A pritchel is a type of punch used in forging, particularly in making nail holes in horseshoes. The horseshoe is heated and a hole is punched through 90 percent of the steel with a forepunch or drift punch. The pointed end of the tool should be kept sharp so that the burr is cut out smoothly.
As the screw enters the plug, the soft material of the plug expands conforming tightly to the wall material. Such anchors can attach one object to another in situations where screws, nails, adhesives, or other simple fasteners are either impractical or ineffective. Different types have different levels of strength, and can be used on different ...

A self-tapping screw is a screw that can tap its own hole as it is driven into the material. More narrowly, self-tapping is used only to describe a specific type of thread-cutting screw intended to produce a thread in relatively soft material or sheet materials, excluding wood screws .
