Anchor nuts are hardware fasteners with a threaded hole that can be attached to a work surface with rivets or screws. They are an alternative to driving threads into a work surface and ensure exact placement of nuts or screws. Anchor nuts were developed to address issues in the aerospace industry and are also used […]
Anchor blocks are used in construction to fasten materials together without compromising the integrity of the structure. They can be made of various materials, such as wood, steel, or aluminum, and are commonly used to attach wooden beams to brick or concrete walls. While other methods have emerged, anchor blocking remains a proven and useful […]
An anchor ball is a buoyant ball with a ring used to retrieve an anchor. It is useful for small boats lacking equipment to carry the line and can save time and energy. Safety precautions should be taken to avoid entangling the anchor line in the boat’s propellers. An anchor ball is a piece of […]
Drop-in anchors are fasteners used to attach items to concrete or masonry surfaces. They consist of a hollow sleeve with an expandable skirt, an expansion plug, and a thread attachment. A suitable hole is drilled, and the anchor is inserted and expanded using a tool. They are easy to install and can carry considerable loads. […]
An anchor flange is used to prevent axial movement in pipelines caused by liquid flow and temperature changes. It is commonly anchored to a concrete foundation and placed at turns or bridge crossings. It can also be used in smaller hydraulic hardlines and is secured by bolting to machines or buildings. The flange is typically […]
An anchor shackle is a type of U- or O-shaped metal piece used to secure a moving object to a stationary one. It has a gate for closure and can be bolted or pinned shut, or spring-loaded. The rounder the shackle, the better it balances forces on it. A shackle is a U- or O-shaped […]
Anchor lights are required by law and recommended for safety. They should be bright white and highly visible to avoid collisions with other ships. Neglecting anchor lights can lead to fatalities, and they are just one of several marine lighting requirements. An anchor light is a light that shows a ship at anchor. Anchor lights […]
Sea anchors stabilize boats by catching water and slowing them down, using drag to keep them on course. They are made from parachute material and can be easily assembled in an emergency. They are vital in high seas and storms, and can also be used to prevent drift and conserve fuel. A sea anchor is […]
A mushroom anchor is a heavy metal object shaped like a mushroom that is used to anchor a ship in areas with sandy seabeds. It was first used on the Pharos ship in the 1800s and requires a counterweight to be buried. It is a permanent anchor and can displace a large amount of material, […]
Anchor buoys are floating objects attached to anchors, with two main types: anchor retrieval and mooring. They vary in size and material, and are often brightly colored. Retrieval buoys help lift anchors, while mooring buoys are secured to the ocean floor and used to moor boats. In nautical terms, an anchor buoy is a floating […]
Anchor bolts connect objects and structural elements to concrete, with different styles available for different applications. Cast-in-place bolts are driven into wet concrete, while others require a hole and can be secured with epoxy or a wedge. Local building codes dictate their size and placement. Once in place, they cannot be easily removed. Anchor bolts […]
Wedge anchors are fasteners used to secure objects to concrete or masonry structures. They consist of a metal bolt and sleeve, and are selected based on load and surface conditions. Installation requires drilling a hole, cleaning the surface, tapping the anchor into place, and rotating the base to wedge it securely. A wedge anchor is […]
Anchor plates are used in masonry buildings to distribute tension and stabilize walls. They are connected to a rod or bolt and are usually visible from the outside. The plates are wide and flat, with a hole in the center for the rod or bolt. They are often decorated and made of cast or wrought […]
Screw anchors are used to provide a secure grip for screws in thin, light, or brittle surfaces. They prevent screws from coming out and can be applied from the outside of a surface. Expansion anchors provide pressure and prevent sliding. Self-drilling anchors can be screwed directly into walls. Users must drill appropriate holes for other […]
Expansion plugs are used instead of screws or nails to secure objects to walls, floors, or ceilings. They expand during installation to grip the surrounding surface, ensuring a secure bond. They can be used in wood, masonry, and even drywall. Metal expansion anchors are needed for concrete or masonry. Single and double expansion anchor models […]
Sleeve anchors are fasteners used to secure objects to concrete or masonry structures. They consist of a metal screw or stud with a cone-shaped tip that flares out to the sides and a metal sleeve that wraps around the pin. The installation process involves drilling a hole, removing debris, inserting the anchor, and tightening it […]
The terms “anchor baby” and “jackpot baby” are used pejoratively in the US to refer to children of undocumented immigrants, but they do not guarantee citizenship for their parents. The law granting citizenship to children born in America is found in the 14th Amendment to the US Constitution. The terms “anchor baby” and “jackpot baby” […]
Anchor links are internal links that allow users to jump to different parts of a webpage. They are useful for large pages and can be created easily with HTML code. Matching link and anchor names is important, and including a link to the top of the page is recommended. Anchor links are a useful tool […]
Anchor text is the visible text in a hyperlink that links to another web page. It is important for navigation and search engine rankings. Using targeted keywords in anchor text can increase website traffic and rankings. Specialized keyword research tools can help in creating effective anchor text.

An anchor test assesses a person’s knowledge or cognitive abilities by testing the same skill or ability in multiple ways to determine if a question was missed due to a gap in knowledge or a misunderstanding of the question. Psychometrists use anchor tests to reliably test skills and eliminate inconsistencies. Traditional tests reveal missing skills, […]
