Thread Size: 8mm; Thread Pitch: 1.25mm; Screw Length: 40mm (measured from under the head); Thread Coverage: Partial Thread
Hex Drive Size: 13mm; Package Includes: 10 Sets
Heavy-Duty Material: 10.9-grade alloy steel bolts withstand up to 1,000 MPa tensile strength; Heat-treated for durability in high-torque applications like suspension systems or industrial gear
Complete Fastening Solution: 10 pre-assembled sets include flange hex bolts, matching nuts, flat washers, and lock washers—ideal for automotive repairs, farm equipment, or machinery assembly. Eliminates mismatched parts and simplifies storage; Flange design integrates a washer-like base, speeding installation without extra tools
Vibration-Proof Design: Serrated flange base bites into surfaces, while lock washers maintain tension under stress. Perfect for engine components, chassis repairs, or rotating machinery where vibrations compromise standard fasteners
