It's also how they get users with critical applications to rotate their stock to avoid having it expire. The factory I work in mainly uses fasteners with lockpatch pre-applied now but I can assure you our quality department wouldn't let expired product be used for any reason.Don't be too concerned with the expiry date I have Loctite that's over 10 years old and still works fine. This is how the manufacturer gets you buy more product.
Not unlike the “Best By” and “Sell By” dates: Sell By gives you a couple of days to consume, how many is up to you and your individual health issues. Best By is the approximate date through which the product will still taste/perform as expected, like canned food: in theory, as long as it hasn’t spoiled (bulged can), it will still be safe to eat, but may have off flavors and lose nutrients.It's also how they get users with critical applications to rotate their stock to avoid having it expire.

Sometimes Loctite is used as a precaution on non-critical applications, sometimes failure could lead to deadly consequences. It's up to the user to make informed decisions on the products and application, but for something with such potentially profound implications it's wise for the manufacturer to specify a shelf life.

Won’t argue with this logic for food or OTC medication. When I had my Bloody Mary drink mix company I had to put these dates on my package even though I was essentially selling salt with spices and freeze dried kale.Not unlike the “Best By” and “Sell By” dates: Sell By gives you a couple of days to consume, how many is up to you and your individual health issues.
