Monster Overview:

Fix your project right the first time with M3-0.5 ISO 14581 6-Lobe (Torx) Flat-Head Machine Screws in heat-treated Class 8.8 steel. These full-thread screws reach ≈ 116 ksi (800 MPa) tensile strength and feature a Zinc-Plated & Baked finish for bright appearance, added corrosion protection, and a post-plating bake to relieve hydrogen embrittlement. Perfect for electronics, industrial equipment, and machinery builds requiring flush mounting, high clamp loads, and reliable torque transfer.

Monster Bolts backs every screw with strict quality control, rapid U.S. shipping, and customer-first support, making us the trusted source for professionals and DIYers alike.

Monster Features:

  • High Strength: Heat-treated Class 8.8 steel (≈ 116 ksi tensile / 92 ksi yield) handles heavy-duty clamping.
  • Finish: Zinc-Plated & Baked (RoHS-compliant) for moderate corrosion resistance and reduced hydrogen-embrittlement risk.
  • Drive: Internal 6-lobe (Torx T10) resists cam-out and allows higher torque than Phillips or slotted drives.
  • Head Style: 90° countersunk flat head sits flush for a snag-free, professional assembly.

Monster Specifications:

  • Diameter × Pitch: M3 × 0.5 mm
  • Length: Available in multiple lengths — please select from the drop-down menu above.
  • Thread: Full thread
  • Standard: ISO 14581
