Bolts designed to deliver consistent strength and corrosion resistance for small mechanical and DIY repairs, meet Valorada M4 Bolts. Confident fastening reduces fiddly rework and keeps assemblies secure during use. Are these M4 hex socket cap screws the reliable choice for 3D printers, RC cars and general household repairs?
⚡ At a Glance
- • Material Strength: High-hardness 12.9 Grade alloy steel for superior tensile strength
- • Best for: 3D printers, RC cars, DIY repair and light machinery maintenance
- • Not ideal for: Heavy structural applications requiring specialised fasteners
Full threads and precise M4-0.7 specification ensure consistent fit. Black oxide finish adds rust resistance for longer service life.
Long-lasting Strength – Thanks to 12.9 Grade alloy steel
12.9 Grade alloy steel denotes a high-hardness material with elevated tensile capability and wear resistance. Manufacturing to that grade reduces risk of deformation under high clamping loads.
Durable clamping reduces fastener failure in assemblies that see repeated use or vibration.
Secure Torque Transfer – With Allen hex socket drive (3mm)
Allen hex socket drive concentrates torque at the head bore, permitting higher tightening force with reduced cam-out compared with simple head types. The 3mm drive size suits common hex keys used in small assemblies.
Accurate tightening helps achieve consistent thread engagement, useful when assembling printers, electronics and small machines.
Reliable Fit and Versatility – With M4-0.7 full threads, 20mm length
Thread diameter 4mm with 0.7mm pitch and a 20mm thread length conforms to standard M4 specifications. Full threads along the shank ensure maximum engagement with nuts and tapped holes.
Consistent compatibility across common M4 fittings makes these bolts handy for multiple repair and DIY scenarios.
