If you've got fitness equipment that uses those pull-pin knobs for height adjustments, this 5-pack of M16 replacements will save you so much hassle! These knobs have that familiar ball shape that's comfortable to grip, with a built-in spring mechanism that locks securely into position when extended. The M16 x 1.5 thread size fits most stationary bikes, weight benches, and other gym equipment that needs quick height adjustments. Each knob has a steel shaft and ABS plastic handle, making them sturdy enough for regular use but lightweight at the same time. The spring action is smooth but strong - pulls out easily when you need to make adjustments but snaps back firmly to stay in place. At about 2.56 inches total length with a 0.79 inch screw section, they're the perfect size for most applications. Installation is straightforward - just screw out your old worn-out knob and screw this one in. No special tools needed. Having five in the pack means you can replace multiple knobs on different machines or keep spares for when others wear out. The black color blends with most equipment, and the smooth edges mean no scratched hands during adjustments. Whether your current knobs are broken, missing, or just getting loose and unreliable, these replacements will have your equipment adjusting smoothly again. Perfect for home gym owners, fitness centers, or anyone tired of struggling with faulty adjustment mechanisms. Much cheaper than replacing entire pieces of equipment just because one small part failed!
