    Load-Rated Reinforced Threaded-Stud Bumpers

    Image of Product. Front orientation. Bumpers. Load-Rated Reinforced Threaded-Stud Bumpers, Style 1.

    Style 1

    These bumpers are tested to ensure they'll support the load of your application. They'll bear the weight of everything from a 50-pound saw to a 5,000-pound air compressor. All have a metal base plate for added strength and a longer service life than all-rubber bumpers. No separate fasteners are needed—just twist them into a threaded hole.

    These bumpers absorb impact well enough for most applications. However, they're not for use outdoors and break down when exposed to oil and harsh chemicals.
    Hardness Rating—The harder the bumper, the better it withstands impact and abrasion over time. The softer the bumper, the more cushioning it provides for objects made of glass, soft metal, and other fragile materials. Bumpers with a medium rating offer a balance of impact resistance and cushioning.
