    Safety pins.

    Even that its really difficult to remove pin, when there is weight on it. Personally i think, nearly impossible.

    But, because there is always that small possibility, i made new safety pins to stands.

    Now, its really difficult to even imagine that pins could be removed accidentally when there is weight on the stands.
    You really need to work for it to make it happen.

    Harbor Freight has a recall on 3 ton and 6 ton jack stands for a collapsing issue,
    https://www.roadandtrack.com/car-cu....of-collapsing/

    The Harbor Freight jack stands that we've all bought, borrowed or seen in our friends' garages are being recalled due to a risk of collapsing under load. Go check yours immediately.
    In a recall filed with the NHTSA on March 20 of this year, Harbor Freight explains that certain 6-ton jack stands have the potential to disengage their support pawl under shifting weight, causing the stand to drop suddenly. A second recall, filed May 3, extends the recall to 3-ton jack stands. The defect is attributed to aging tooling at the factory that produced the jack stands.

    Harbor Freight
    The recall document says that the problem could affect more than 450,000 6-ton jack stands produced between 2013 and 2019 and nearly 1.3 million 3-ton jack stands produced between 2012 and 2020. These jack stands were sold under the Pittsburg brand name, and can be identified by item numbers 56371 or 61196 on 3-ton models, and 61197 on 6-ton models.
    Harbor Freight urges anybody in possession of affected jack stands to return them to the store in exchange for a gift card equal to the price of the stands. Any unsold jack stands covered by the recall have been removed from stores. Check on your buddies and spread the word around—these jack stands are ubiquitous, and a failure like this could be fatal.

    It is really important that people see this.

    Beyond that jack stands are rated in pairs, which many do not realize. The ASME standard is rather BS so I'm not sure we can blame china on this one. At one time there was a tonnage cut off, for the pair rating, but in the end I honestly believe most home made stands are actually safer than the commercial stands. I do believe the standard was updated, possibly in 2015, so those old jack stands are not worth a dime. Somethings should only be recycled.

    Yea, i bought some 3 ton jack stands from hf about 5 months ago. They were a new number according to the employee. So i bought them. Glad i did because their number is not on the list, so far. But the design and operation is all wrong to me. There is no engagement of the teeth. The engaging pawl only jams against the teeth. So i may still return them if i can find a proper reasonable set of stands.

    Yeah, I guess that's possible; when the tooling is third rate to start with.
    Take auto manufacturing for example; castings, forgings, formed parts, stampings, drawn parts,...name a previous occurrence of 'aging tooling', especially safety items had such an excuse after less than half-million products. I've never seen a high volume fixture that did not have records monitoring usage, rejections, or maintenance.
    Another fine example of a less than global mindset on the part of CEO's, factories and importers.
