❓ Frequently Asked Questions
Q: What makes M16 nuts "heavy duty" compared to smaller sizes? 🏗️
A: M16 nyloc nuts are considered heavy duty due to their 16mm thread diameter and corresponding 24mm spanner size. They're designed for structural applications, supporting heavier loads than smaller fasteners. The larger size provides greater clamping force, higher shear strength, and increased vibration resistance for machinery and construction applications.
Q: What torque should I use for these M16 nyloc nuts? 🔧
A: For M16 A2-70 nyloc nuts, typical torque ranges from 140-170 Nm (103-125 ft-lbs) for dry threads. With lubrication or anti-seize, reduce torque by 20-25%. Critical applications require engineering specifications. Always use a calibrated torque wrench and consider factors like material strength, bolt grade, and application requirements.
Q: Are these suitable for structural steel applications? 🏗️
A: Yes, our M16 nyloc nuts are suitable for many structural applications when used with appropriate M16 bolts. However, for primary structural connections in buildings, bridges, or critical infrastructure, always consult project engineers and follow specific design specifications, which may require certified structural nuts with documented mechanical properties.
Q: What tools do I need for installation? 🔩
A: For M16 nyloc nuts, you'll need 24mm tools: combination wrench, socket (1/2" or 3/4" drive recommended), and preferably a torque wrench capable of 140-170 Nm. Impact wrenches work but may affect nylon inserts. For structural applications, calibrated torque wrenches are essential for proper installation and safety.
Q: How many times can I reuse these in heavy duty applications? 🔄
A: In heavy duty applications, expect 5-8 reuses maximum. The nylon insert experiences greater stress in structural applications. Always inspect the insert before reuse. For critical structural connections, many engineers recommend single-use only. The 20-pack provides sufficient nuts for multiple installations and replacements.
Q: Can these be used with galvanized or painted bolts? 🎨
A: Yes, but thickness matters. M16 nyloc nuts work with galvanized or painted M16 bolts, but coating thickness affects thread engagement. The nylon insert may not seal properly if coatings are too thick. For optimal performance, ensure bolts are within standard dimensional tolerances. Test fit before critical installation.
