JIS Steel Pan Head Screws

These screws are manufactured to meet Japanese Industrial Standards. Similar in appearance to Phillips, the JIS drive has a shallower opening with sharper angles and straighter internal walls. This lets them withstand more torque while preventing the driver from slipping and damaging the drive. Tighten them only with a JIS driver to avoid stripping the drive. Some JIS screws are marked with a dot near the drive for quick identification. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads.

Length is measured from under the head.

Zinc-Plated Steel—A common choice for areas with occasional exposure to moisture.

Stainless Steel Hex-Drive Precision Shoulder Screws

Our go-to choice for assemblies that require smooth, accurate movement. These screws are engineered for tight tolerances, with shoulder diameters twice as precise as those on standard-fit screws. They're made of stainless steel, so they won't rust, though they're not as strong as their alloy steel counterparts.

18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they won't hold up to the harsh chemicals that 316 stainless steel can.
