M4 bolts
As technology continues to evolve and components and devices shrink in size the need for small bolts has become more apparent. We stock some of the smallest bolt sizes currently available on the market, within our small bolt category. This includes m1 bolts, m2 bolts, m3 bolts, and m4 bolts. Despite their small size, our M4 bolts have a premium build quality and are constructed from high quality grades of A2 and A4 stainless steel. The use of such a high quality material gives these small bolts an excellent blend of strength and durability, along with a pleasing aesthetic appearance.
An m4 bolt is the largest bolt in our specialist small bolt category range. With a 4mm thread width, they are commonly used as tv bracket screws and tv mount screws. However, m4 bolts are a useful size that are commonly used in manufacturing and the assembly of many different electronic devices. The first class build quality of our m4 bolts gives them a use case across many different industrial, commercial and domestic applications.
What are m4 bolts used in?
M4 stainless steel bolts have a 4mm thread size. M4 bolts are a popular size that is useful for a plethora of fastening applications. These small bolts are in strong demand across consumers and businesses due to their strength and corrosion resistance. Some examples of applications include:
- Automotive: There are numerous sensors in cars and vehicles that require very small bolts to secure their components. M4 bolts are commonly used for this purpose.
- Precision manufacturing: M4 bolts are commonly used in precision manufacturing during the assembly of small devices and intricate components. Their size provides a small bolt that can still be reliably handled by manufacturing equipment and machines.
- Semiconductors: You may also see m4 bolts used in the production of semiconductors, where precision is essential.

Are m4 bolts the same as m4 screws?
Customers looking for m4 screws will also find our range of m4 bolts useful. This is due to both terms referring to a similar set of products - essentially small fasteners with a 4mm thread width. This is a metric size which uses millimetres to measure thread size, as opposed to inches which are used in the US and other regions.
Our m4 bolt category will also be useful for customers who are searching for m4 countersunk bolts and m4 countersunk machine screws. We stock a superior range of m4 bolt thread lengths including popular sizes such as m4 20mm screws and m4 60mm bolts. If you don't see the specific thread length that you require, please contact us.
