sturiz 12pcs M5 Hex Head Screw Bolt with Nuts Flat & Lock Washers Kits M5x50mm Stainless Steel Nuts and Bolts Nuts and Washers Coach Bolts for DIY Equipment Machinery

• Complete Set of Accessories: You will receive 12 sets of bolt, comprising 12pcs M5x50mm bolts, 12pcs M5 spring washers, 12pcs M5 hex nuts, and 12pcs M5 washers. This comprehensive nuts and bolts set provides ample components to meet diverse fastening requirements for daily installation, maintenance, and assembly tasks.
• Premium Materials: These hex bolts, nuts, spring washers, and washers are crafted from 304 stainless steel (A2 / V2A). The stainless steel nuts and bolts resist rust, corrosion, and oxidation, resist deformation and breakage, distribute stress evenly, and deliver stable fastening performance. Nuts and washers suitable for equipment installation, mechanical assembly, and diverse outdoor/indoor applications, these bolts provide reliable material assurance for all fastening requirements.
• Simple Installation: When fitting hex bolts, thread the bolt through the pre-drilled hole. Place a flat washer or spring washer as required, then tighten the nut using a spanner to secure the connection. The precision-machined threads feature uniform pitch and clear thread profile, ensuring smooth insertion for a secure and reliable joint. The entire installation process is straightforward and intuitive. Upon completion, verify component alignment and tighten to the appropriate torque.
• Versatile Applications: Fully threaded hex bolts are suitable for home renovation, automotive maintenance, and various DIY craft projects, serving to secure furniture, mechanical components, and structural connections. These coach bolts provide stable fastening across diverse materials including metal, timber, and plastic. Whether for everyday household use or factory assembly and repair, bolts and nuts deliver enduring fastening performance, balancing practicality with universal applicability.
• Secure Connection: Hex nuts possess excellent load-bearing capacity, providing stable force transmission; flat washers effectively increase contact area, evenly distributing pressure; lock washers reliably prevent loosening caused by vibration or prolonged use. The complete nut-bolt assembly works in concert to form a robust and dependable connection, suitable for various installation and mechanical applications demanding high stability and load-bearing capability.

Precautions for Using Bolts and Nuts: 1. Prior to installation, verify that the dimensions of bolts, nuts, and washers match the hole diameter and thread pitch to prevent compromised fastening due to mismatched specifications. 2. Employ appropriately sized wrenches or socket tools for tightening to prevent slippage or damage to the hexagonal head caused by mismatched tools. 3. Apply force progressively during tightening to avoid over-tightening, which may result in stripped threads, deformation, or fastener failure. For high-load applications, installation to specified torque values is recommended. 4. Prior to installation, ensure connection surfaces are clean, flat, and free from oil or contaminants to guarantee even force distribution and enhanced joint stability. 5. In damp or corrosive environments, conduct regular inspections of fastening integrity. Perform maintenance or replacement as necessary to ensure long-term safe and reliable operation.
