Long-lasting strength – thanks to 10.9 grade carbon steel
Manufactured from high-quality 10.9 grade carbon steel, the fasteners are specified as strong and durable in the product description. The grade indicates robust mechanical properties suited to repeated fastening and load-bearing use.
Durable components reduce the need for frequent replacements, so repair work holds up over time. Suitable for mechanical, automotive and electromechanical applications where stronger fasteners are required.
Secure assemblies – with hex socket button head cap screws
Button head Allen screws feature a wide load-bearing surface and clear threads for even force distribution, and a hex wrench is included for straightforward tightening. The socket design helps assembly in confined spaces.
Wide bearing surfaces lower the chance of loosening under stress, producing neater, more reliable joints. Quick assembly and disassembly make maintenance faster for small machines and equipment.
Ready for varied M3 projects – with multiple lengths, nuts and washers
The package contains screws in several lengths (6mm–30mm), plus a large number of matching M3 nuts and flat washers, plus a wrench for installation. Quantities are listed for each length and accessory.
Generous counts let users complete several repairs or builds without hunting for extra parts. Keeps multiples of the same diameter handy for projects that need consistent fastener sizing.
