Okay, for all you mechanics and DIYers who need left-hand thread bolts, this uxcell M12x35mm hex bolt is exactly what you're looking for! The left-hand reverse thread design means you turn it counter-clockwise to tighten and clockwise to loosen - which is the opposite of standard right-hand threads. This is crucial for certain applications where regular threads might loosen due to vibration or rotation in the 'wrong' direction. Made from carbon steel with an 8.8 grade rating, this is a serious industrial-grade bolt that can handle substantial loads and stress. The black oxide plating provides decent corrosion resistance while maintaining that professional, finished look. The full threading along the entire 35mm length gives you maximum flexibility in how deep you can sink the bolt into materials. The hex head is 18mm across, providing good leverage for tightening without being so large it looks out of place. Weighing 40 grams, it's substantial enough to feel quality but not overly heavy. These left-hand thread bolts are essential for specific machinery, equipment maintenance, and certain automotive applications where reverse threading is necessary for safety or function. The 1.75mm pitch is standard for M12 bolts, ensuring compatibility with corresponding nuts and threaded holes. Whether you're working on industrial equipment, automotive projects, or specialized machinery that requires left-hand fasteners, having the proper thread direction is critical for safety and proper function. This single bolt comes ready to solve that specific fastening problem that right-hand threads just can't handle properly.
