M5-0.8 x 40 Cup Point 18-8 Stainless Steel Metric Socket Set Screw is a headless internal-hex fastener for locking collars and hubs in wet metric equipment.
Knobs and levers on wet-area controls use headless socket set screws to avoid an external wrenching head. Some imported metric drawings refer to A2 stainless; use the actual drawing language and service conditions when confirming the part. 316 metric set screws can be quoted for chloride and marine service as a non-catalog request. Confirm the metric thread, length, cup diameter, and hex key before substituting another set screw.
Cold Headers supports imported equipment rebuilds where the replacement screw must preserve the original metric callout.
