Are these M6 flanged button head socket cap screws the right choice for your next build, repair or restoration project? sourcing map Flanged Button Head Socket Cap Screws
⚡ At a Glance
- • Holding Strength: Flanged button head spreads load across a larger surface while full threading ensures firm engagement along the 45mm shaft
- • Best for: Furniture assembly, machinery maintenance and electronics fastening where a neat, low-profile finish matters
- • Not ideal for: Situations needing captive or countersunk fastenings rather than a button-head appearance
M6 x 45mm fully threaded socket cap screws with a flanged button head. Made from 304 stainless steel for corrosion resistance and suitable for indoor and outdoor use.
Corrosion-resistant durability - with 304 stainless steel construction
304 stainless steel offers high hardness and stable material performance, resisting corrosion and tolerating higher temperatures. The alloy is commonly used where moisture exposure might cause weaker steels to fail.
Long-term use in humid or outdoor environments without rapid surface degradation. Less frequent replacement and lower maintenance for assemblies exposed to damp conditions.
Secure, low-profile fastening - thanks to flanged button head design
A flanged button head increases the bearing surface and distributes clamping force more evenly across the joined material. The design also helps limit over-tightening by providing a larger contact area under the head.
Neat finishes on visible joins and reduced risk of crushing softer materials when torquing. Ideal where a tidy appearance must accompany reliable clamp force.
Consistent engagement and simple fitting - with fully threaded M6 x 45mm specification
Each screw is fully threaded to the head with a pitch of 1mm, an inner hex diameter of 4mm and a head size of 10.3 x 3.1mm, enabling standard hex key installation. The flange diameter measures 13.5mm for broad load distribution.
Predictable threading behaviour when matching with tapped holes or nuts, and quick installation using a 4mm hex wrench. Suitable when fast, repeatable assembly is required.
