Fasteners designed for secure, low-profile connections in compact assemblies. Peace of mind for DIYers and tradespeople who need neat finishes and consistent fit. Are Screws City Button Head Screws the dependable M5 choice to keep in the toolbox?
⚡ At a Glance
- • Tensile Strength: Grade 10.9 high tensile steel with zinc grade finish per ISO 7380-1
- • Best for: Small assemblies, furniture fittings and repair jobs needing neat, low-profile fixings
- • Not ideal for: Applications requiring integrated sealing or specialised corrosion resistance
High tensile 10.9 steel and a zinc grade finish meet ISO 7380-1 standards. M5 x 8mm size, 0.8mm pitch and a 3mm Allen drive deliver predictable fit and easy installation.
Secure clamping - thanks to high tensile 10.9 steel
Grade 10.9 identifies a high-tensile classification for the steel used, giving greater resistance to shear and overload than lower grades. Compliance with ISO 7380-1 indicates consistent manufacturing tolerances.
Stronger material reduces the chance of fastener failure under load, so joints remain secure during everyday use and light mechanical stress.
Neat, low-profile finishing - with button head and 9.14–9.5mm head diameter
Button head geometry spreads load across a wider area while keeping the head height low, and the specified head diameter range ensures a consistent visual result.
Fastened assemblies look tidier and are less likely to catch on clothing or components, useful where a smooth surface matters.
Accurate fit in tight spaces - with M5 x 8mm sizing, 0.8mm pitch and 3mm Allen drive
M5 thread diameter paired with a 0.8mm pitch matches standard M5 nut and tapped-hole profiles; the 3mm Allen socket gives a positive driver engagement.
Fasteners can be driven with controlled torque in confined areas, making installation quicker and reducing the risk of stripping.
