Description:Material – Flat washers are made of carbon steel with zinc plating on the surface, no burrs, strong and durable, with excellent wear resistance, rust resistance, and corrosion resistance, reducing the need for frequent maintenance and replacement.Function – Metal flat washers are designed to provide a wider bearing surface for bolts, screws, and nuts, used to carry the load of threaded fasteners over a larger surface area. This helps prevent damage to the connecting material and reduces the risk of concentrated force.Easy to Use – Flat washers are commonly used under bolts or nuts to secure bolts with a smaller diameter than the washer hole to provide a smooth bearing surface and reduce the possibility of the fastener loosening due to contact with uneven surfaces.

Reaming Drill BitGeneral Information：[1]Uncoated Reamer Drill Bit: Features just the base substrate without any additional coatings, used on a wide range of materials. Tapping fluid or cutting oil can be used to lubricate the reamer and workpiece to help reduce friction and increase tool life.[2]Wide Applications: The reamer is designed to accurately enlarge, smooth or finish holes in stainless steel, cast iron, aluminum, non-ferrous metals, plastic, and wood, widely used in hole repair work, pipe and fittings, woodworking applications.[3]Hand Reamer: The reamer drill bit can be hand operated by use of a wrench, T-handle wrench, extension rod, drill chuck. Used for light cut, repair work, removing stock or simply for enlarging holes.
4-point drive socket is made of sturdy CR-MO alloy steel forging, which has high tensile strength and wear resistance, effectively absorbs impact, is not easy to deform or damage, and is suitable for working environments with high torque. The blackening surface is high-temperature phosphating, helping to prevent rust and corrosion, thereby extending the tool’s lifespan.The port of the impact socket adopts a 4-point square structure, which can better fit the square head of the screw or nut, providing a stronger grip when used, preventing the fastener from becoming round, and is not easy to slip. The anti-drop hole design of the base can help the socket be fixed on the tang of the pneumatic wrench or driver to prevent the pin from falling off, making it safer to use.
