Button Screws
Button screws, also known as button head screws, are versatile fasteners designed with a smooth, rounded domed head that provides a modern appearance and excellent load-spreading capability. Their low-profile design makes them ideal for visible installations, furniture assembly, metalwork, electronics, machinery and general engineering tasks throughout the UK. They are also widely referred to as dome headed screws when a decorative or low-protrusion finish is required.
What Are Button Screws?
A button screw features a domed, wide head that distributes load more effectively than a countersunk alternative, reducing stress on the material and minimising the need for washers. The smooth head profile offers a snag-free finish, particularly useful in applications involving frequent handling or contact. These screws are available in a wide range of driver types such as Phillips, Pozi, Torx and hex socket, ensuring compatibility with various assembly requirements.
Styles and Variations
- Standard Button Head Screws: A low-profile domed head suitable for general assembly and engineering tasks.
- Flanged Button Screws: Integrated flange for increased bearing surface, popular in sheet metal work and corrugated roofing.
- Socket Button Head Screws: Hex drive design for improved torque control and secure tightening.
- Dome Head Variants: A smooth, rounded profile ideal for visible or decorative fixings.
Materials and Finishes
We supply button screws in a range of materials to suit different environments and performance needs, including:
- Stainless Steel (A2 & A4): High corrosion resistance for outdoor, marine, chemical and high-moisture environments. These are the ideal choice for customers searching for reliable stainless steel button head screws.
- Zinc-Plated Steel: Economical and suitable for indoor or general construction uses.
- Black Steel / Black Oxide: A discreet finish suited to retail displays, interiors, and modern product designs.
- Alloy Steel: High-strength options for industrial, mechanical and machinery applications.
Common UK Use Cases
- Furniture assembly and panel fixing where a smooth, user-safe finish is required
- Sheet metal fabrication including cladding and corrugated roofing
- Electronics, casings, cabinets and enclosures requiring a clean, professional appearance
- General engineering and automotive tasks where load spreading is essential
- Applications requiring corrosion-resistant stainless steel button head screws for outdoor or marine environments

Frequently Asked Questions
What is a button head screw?
Stainless steel button head screws are fasteners that feature a low profile and rounded design of the screw's head. The shape of the head loosely resembles a button in shape, which has led to this name. This style of screw has been designed to provide a smooth and finished appearance, while still offering surface for tightening with hand tools such as screwdrivers, wrenches or allen keys. Stainless steel button head screws combine a good functional performance with aesthetic appeal, which makes them a popular choice of screw for many fastening applications across multiple industries within the UK.
What types of button head screws are there?
We sell five varieties of stainless steel button head screws. This includes the popular stainless steel hex button head screw. With their six-sided hex drive, these are generally considered to be the standard stainless steel button head screw. We also sell stainless steel button head torx screws and these feature a torx drive, instead of hex. Additionally, we offer flanged hex button screws and a flanged torx button screws. These flanged variations can offer better load distribution and stability in some applications and the flange can serve as a stopper to prevent over-insertion of the screw. Finally, we offer a pin torx stainless steel button head screws, these feature pin torx drives that can be used in applications that need to be tamper-resistant.
What are button head screws also known as?
The first point to note here is that when describing stainless steel button head screws, the term bolt is also used interchangeably by many people. Many customers will known this style of screw head as a dome head, leading to customers calling them stainless steel dome head screws or stainless steel dome head bolts. Another common term for this style of fastener head is a roundhead or round head type. This leads to descriptions like roundhead stainless steel screws and stainless round head bolts. Finally the drive or recess in the screw head is used as a method for distinguishing the type of button head screw. Stainless steel button head allen bolts or stainless steel button head torx screws are two popular examples of this. Many customers searching within the UK market, will simply call them stainless steel button head bolts.
Do you sell m6 stainless steel button head bolts?
Vital parts supplies stainless steel button head screws and bolts in a selection of metric thread sizes. This includes the popular m6 stainless steel button head bolts and m5 stainless button head screws. Our standard catalogue stocks stainless steel dome head screws in sizes from m2 up to m12. However, if you need a size that isn't listed, then please let us know using our contact us form as we are often able to provide additional dimensions.
What is the difference between socket cap screws and button head screws?
There are some important differences between socket cap screws and button head screws. These can be summarised into distinctions in the shape and design of the screw's head that change the appearance and functionality of the two styles of screws. Socket head cap screws have a cylindrical shaped head, while button head screws have a dome shaped head. The Domed style of the iso 7380 screws offers a lower profile head than the din 912 socket cap screw. Additionally, the cylindrical head of socket cap screws can be fitted with knurled heads for increased grip. It isn't possible to add these to the lower profile button head screws. Functionally speaking, the cylindrical shape of the socket cap screws also provides improved torque, meaning that generally socket cap screws can be tightened harder than their button head counterpart. A final key difference in the two styles of screws is their appearances and aesthetics. Socket head cap screws are generally taller than button head screws due to the added size of the cylindrical head, this gives a more utilitarian and industrial look to the fastener. In comparison, the button head screws have a sleeker, rounded head with a lower profile. This design is generally considered to be more aesthetically pleasing, and this can explain the popularity of button head screws and their application in most general projects that don't require to extra torque of socket cap screws.
What are the benefits of using stainless steel button head screws?
Stainless steel button head screws offer excellent corrosion resistance, making them ideal for outdoor, marine and high-moisture environments. Their domed head provides a smooth, low-profile finish while distributing load effectively across the surface. This combination of durability, strength and appearance makes stainless steel button head screws suitable for furniture, metalwork, electronics and general engineering applications.
When should I choose stainless steel button head screws over zinc-plated or black steel options?
You should choose stainless steel button head screws when the installation will be exposed to moisture, chemicals, saltwater or outdoor conditions. Stainless steel provides significantly better corrosion resistance than zinc-plated or black oxide finishes. It is the preferred choice for marine projects, external fittings, food production, chemical environments and any application requiring long-term durability without rusting.
