Buying Guide: 120 x 0.70 Fasteners And Related Components
What to look for when choosing 120 x 0.70 fasteners
Choose stainless steel for corrosion resistance in humid or outdoor environments. Confirm length suits the material thickness and mounting surface. Verify head style (flat head for flush mounting) and drive type (hex socket) for tool compatibility.
Should you pick longer bolts or shorter ones?
Longer bolts like 120 mm are useful for thicker assemblies or when spacers are involved. Shorter bolts reduce protrusion and provide a cleaner finish. Always account for nut, washer, and surface thickness in your calculation.
What about washers and supporting hardware?
Washers distribute load and reduce pull-through risk on soft materials. If you’re using 0.7 mm threads in a heavy load, consider locking washers or thread-locking compounds as needed by the application.
Application-specific tips
- Electronics enclosures: use flat-head screws to sit flush with casings.
- Furniture or cabinetry: stainless steel reduces corrosion in humid spaces.
- Machinery mounting: ensure thread length exceeds material thickness for secure fastening.
Quick FAQ
- What is the significance of a 0.7 mm thread pitch?
Answer: It indicates the distance between threads; 0.7 mm is common for small-diameter fasteners in electronics and light machinery. - Are 120 mm screws suitable for all projects?
Answer: No. They are best when the mounting surface is thick enough to accommodate the full length without bottoming out. - Is stainless steel 304 suitable for outdoor use?
Answer: Yes, it provides good corrosion resistance in many environments, though extreme exposures may require coatings. - What is the advantage of a flat head screw?
Answer: It sits flush with the surface, offering a clean finish and reduced snag risk. - Do I need a hex key for these screws?
Answer: For hex socket drive screws, a matching hex key or bit is recommended for torque control and proper seating. - Can I mix these with other brands?
Answer: It’s best to match thread pitch and diameter; incompatibilities can lead to cross-threading or poor fit.
