Bevel
A bevelled edge (UK) or beveled edge (US) is an edge of a structure that is not perpendicular to the faces of the piece.
Bolt (fastener)
A bolt is an externally helical threaded fastener that fastens objects with unthreaded holes together.
See Countersink and Bolt (fastener)
British Association screw threads
British Association screw threads, or BA screw threads, are a set of small screw threads, the largest being 0BA at 6 mm diameter.
See Countersink and British Association screw threads
British Standard Fine
British Standard Fine (BSF) is a screw thread form, as a fine-pitch alternative to British Standard Whitworth (BSW) thread.
See Countersink and British Standard Fine
British Standard Whitworth
British Standard Whitworth (BSW) is an imperial-unit-based screw thread standard, devised and specified by Joseph Whitworth in 1841 and later adopted as a British Standard.
See Countersink and British Standard Whitworth
Burr (edge)
A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. Countersink and burr (edge) are Metalworking terminology.
See Countersink and Burr (edge)
Chamfer
A chamfer is a transitional edge between two faces of an object. Countersink and chamfer are Metalworking terminology.
Cone
A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex.
Counterbore
In machining, a counterbore (symbol: ⌴) is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature. Countersink and counterbore are Metalworking cutting tools and Metalworking terminology.
See Countersink and Counterbore
Countersink
In manufacturing, a countersink (symbol: '''⌵''') is a conical hole cut into a manufactured object, or the cutter used to cut such a hole. Countersink and countersink are Metalworking cutting tools and Metalworking terminology.
See Countersink and Countersink
In the context of machining, a cutting tool or cutter is typically a hardened metal tool that is used to cut, shape, and remove material from a workpiece by means of machining tools as well as abrasive tools by way of shear deformation. Countersink and cutting tool (machining) are Metalworking cutting tools.
See Countersink and Cutting tool (machining)
Dimple
A dimple, also called a gelasin, and a fovea buccalis, is a small natural indentation in the flesh on a part of the human body, most notably in the cheek.
Drill
A drill is a tool used for making round holes or driving fasteners.
End mill
An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. Countersink and end mill are Metalworking cutting tools.
Engineering drawing abbreviations and symbols
Engineering drawing abbreviations and symbols are used to communicate and detail the characteristics of an engineering drawing.
See Countersink and Engineering drawing abbreviations and symbols
Harmonic
In physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal.
Indicator (distance amplifying instrument)
In various contexts of science, technology, and manufacturing (such as machining, fabricating, and additive manufacturing), an indicator is any of various instruments used to accurately measure small distances and angles, and amplify them to make them more obvious.
See Countersink and Indicator (distance amplifying instrument)
ISO metric screw thread
The ISO metric screw thread is the most commonly used type of general-purpose screw thread worldwide.
See Countersink and ISO metric screw thread
Lathe
A lathe is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, threading and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis.
Machining vibrations
In machining, vibrations, also called chatter, are the relative movements between the workpiece and the cutting tool.
See Countersink and Machining vibrations
Manufacturing
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation.
See Countersink and Manufacturing
Milling (machining)
Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. Countersink and Milling (machining) are Metalworking terminology.
See Countersink and Milling (machining)
Nut (hardware)
A nut is a type of fastener with a threaded hole.
See Countersink and Nut (hardware)
Rivet
A rivet is a permanent mechanical fastener.
Screw
A screw is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to the head.
Sheet metal is metal formed into thin, flat pieces, usually by an industrial process.
See Countersink and Sheet metal
Speeds and feeds
The phrase speeds and feeds or feeds and speeds refers to two separate velocities in machine tool practice, cutting speed and feed rate. Countersink and speeds and feeds are Metalworking terminology.
See Countersink and Speeds and feeds
Spotface
A spotface or spot face is a machined feature in which a certain region of the workpiece (a spot) is faced, providing a smooth, flat, accurately located surface. Countersink and spotface are Metalworking terminology.
Surface finishing
Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property.
See Countersink and Surface finishing
Tap and die
Taps and dies are tools used to create screw threads, which is called threading.
See Countersink and Tap and die
Unified Thread Standard
The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada.
