M6X1.0 Pan Phillips SEMS with Oversized Flat Washer - Stainless
SEMS screw combining a JIS-standard pan head with an integrated oversized flat washer, offering efficient assembly (no need to manually position a separate washer) and reliable clamping force in a single fastener.
The larger surface area of the pre-assembled free-spinning flat washer spreads the clamping force more widely across the material, which helps reduce the risk of pull-through or material damage.
The oversized washer footprint also adds friction and stability in dynamic or high-vibration environments, such as in automotive or machinery applications.
Material
A2 Stainless screws are commonly used in damp environments for corrosion resistance, popular across a wide range of industries: automotive, motorsport, electronics enclosures and control panels, industrial machinery, architectural finish work, agriculture, food processing, clean energy, etc.
Applications
Manufactured to Japanese Industrial Standards (JIS), the screw features a smaller diameter pan head than its ISO or DIN counterparts, making it ideal for applications requiring OEM-style hardware, particularly in Japanese automotive, motorcycle, and machinery restoration.
Also Known As: SEMS screw, washer-head screw, combination screw, or captive washer screw (JIS style)
