M8 A2 Stainless Steel Torx Pan Head Machine Screws — Six Lobe Star Drive for Maximum Torque Control
Cam-out on an M8 fastener is more than frustrating — it can strip the head, damage your workpiece, and halt a project entirely. Whether you're assembling structural brackets, securing enclosures, or building precision equipment, you need a fastener that drives clean and holds firm. These M8 A2 stainless steel Torx pan head machine screws deliver the torque control and corrosion resistance that demanding applications require.
Manufactured to DIN 7985 / ISO 14583, these screws feature a low-profile pan head with a six-lobe Torx (star) recess in M8 diameter. Lengths range from 10mm to 100mm (approximately 0.39" to 3.94"), covering the full spectrum of light-to-heavy duty M8 fastening needs. The A2 stainless steel construction (equivalent to 304 grade) delivers solid corrosion resistance without coatings that can chip or flake under load.
Ideal for structural fabrication, machinery assembly, HVAC installations, automotive components, and general engineering — these M8 Torx pan head machine screws are a reliable choice for workshops, maintenance teams, and professional builders. Order single screws for precision builds or bulk packs of up to 100 for production runs.
🔩
Compatible with standard M8 metric nuts, threaded inserts, and tapped holes. Requires a Torx (TX/T) six-lobe star driver bit — typically T40 for M8.

❓ Frequently Asked Questions
What sizes are available for these M8 Torx pan head machine screws?
These M8 screws are available in lengths from 10mm to 100mm (approximately 0.39" to 3.94"), covering a wide range of fastening applications. Use the Size(mm) dropdown to select your exact length.
What material are these screws made from?
These screws are manufactured from A2 grade stainless steel (304 equivalent), providing excellent corrosion resistance for indoor and general outdoor use. The natural stainless finish requires no additional coating.
What Torx bit size do I need for M8 Torx pan head screws?
M8 Torx pan head machine screws typically require a T40 Torx (six-lobe star) driver bit. Always verify the correct bit size with your specific screw before driving to avoid head damage.
Are these screws suitable for outdoor use?
A2 stainless steel generally provides good corrosion resistance for most outdoor environments including light moisture exposure. For highly corrosive, coastal, or marine environments, A4 (316) grade stainless is typically recommended.
What standard do these screws conform to?
These screws conform to DIN 7985 / ISO 14583, the metric standard for pan head screws with Torx and cross recesses. This ensures dimensional consistency and compatibility with standard M8 nuts, washers, and tapped holes.
Why choose Torx drive over Phillips or Pozi?
Torx (six-lobe star) drive provides superior torque transfer and virtually eliminates cam-out, which is especially important for larger M8 fasteners under high torque. This protects both the screw head and your driver bit, extending tool life and reducing installation errors.
What quantity options are available?
These screws are available in quantities of 1, 3, 5, 30, and 100 pieces, allowing you to order exactly what your project requires — from a single replacement to a full production run.
