The spelling of the word "hanger bolt" may seem unusual, but it is based on its pronunciation. The IPA phonetic transcription of this word is /ˈhæŋər ˌboʊlt/. The first syllable "hang" is pronounced with the vowel sound /æ/, like in the word "cat". The second syllable "er" has the schwa /ə/ sound. The final syllable "bolt" is pronounced with the /oʊ/ diphthong, like in the word "boat". This bolt is commonly used to hang items and is often found in furniture assembly.
A hanger bolt is a type of fastener that consists of a long threaded shank with a lag screw thread on one end and a machine screw thread on the other. This unique design allows the hanger bolt to be used as both a screw and a bolt, combining the characteristics of these two types of fasteners into a single item.
The lag screw thread on one end is typically coarse and self-tapping, intended to be screwed directly into wood or other similar materials, providing a sturdy and secure connection. The machine screw thread on the other end is finer and is meant to be used with a nut or threaded insert.
Hanger bolts are commonly used in applications where the need for secure fastening is essential, particularly in construction and woodworking industries. They are often used to attach objects to wood, such as hanging heavy items like ceiling fans, light fixtures, or shelves. The lag screw thread provides stability and prevents the hanger bolt from easily pulling out, while the machine screw thread allows for easy adjustment or removal if needed.
Hanger bolts are available in various sizes and materials, including steel, stainless steel, and brass, to suit different applications and requirements. They are typically installed using a wrench or socket on the machine screw end while the lag screw end is driven into the wood using a screwdriver or drill.
Overall, hanger bolts are versatile fasteners that provide both the strength of a lag screw and the flexibility of a machine screw, making them an essential tool in many construction and woodworking projects.
The word "hanger bolt" derives from the combination of two separate words: "hanger" and "bolt".
The term "bolt" comes from Old English "bolt", which originally referred to a short, stout arrow or dart. Over time, "bolt" expanded its meaning to a metal rod or pin used for fastening or securing objects together.
The term "hanger" originates from Middle English "hangere", which meant a person or thing that hangs or is suspended. It also referred to a bracket or hook from which something can be hung or supported.
When these two words are combined, "hanger bolt" refers to a type of bolt that has a threaded section on one end and a lag screw thread on the other. It is primarily used for hanging or attaching objects to different surfaces, such as mounting shelves, mirrors, or light fixtures.
