Fasteners for repair and assembly that deliver secure clamping and corrosion resistance. DTGN Button Head Socket Cap Screws suit cyclists, mechanics and hobbyists who need dependable replacement fasteners for routine maintenance. Are these M6 hex-socket screws the right choice for workshop and on-the-road repairs?
⚡ At a Glance
- • Holding Strength: Coarse M6 x 1mm thread combined with dome head and inner hex drive gives higher torque and strong clamping force
- • Best for: Mechanics, cyclists and DIYers needing reliable replacement fasteners for bicycles, motorcycles and cars
- • Not ideal for: Applications that require stainless steel fasteners for constant salt-water exposure
M6 coarse-thread button head socket cap screws made from carbon steel with black oxide treatment. Inner hex drive and dome head increase torque and bearing surface for secure assemblies.
Secure clamping – thanks to inner hex drive and dome head
Inner hex drive allows higher torque transfer from wrench to screw while the dome head provides a wider bearing surface that spreads load across the joint. Coarse M6 x 1mm thread grips into mating parts for firm retention.
Stronger clamping reduces loosening under vibration, ideal for bike and engine assemblies where secure joints matter.
Durable finish – with carbon steel construction and black oxide treatment
Carbon steel gives tensile strength suitable for common mechanical uses, while black oxide adds a darker surface finish that slows corrosion compared with bare steel. The treatment also improves appearance and reduces friction during installation.
Longer service life and a more resilient exterior help the screws withstand routine wear in workshops and outdoor use.
Ready for replacements – thanks to standard M6 sizing and 20-piece pack
Thread diameter M6, pitch 1mm and a 50mm length match standard coarse-thread applications, supplied in a set of 20 for multiple repairs or projects. Head diameter and hexagon width conform to common tool sizes.
Bulk supply simplifies maintenance tasks and makes it easy to replace worn fasteners without sourcing individual parts.
