Commercial gym, home and outdoor fitness devices suffer long-term vibration, sweat and damp exposure. Carbon steel bolts easily rust and jam, while 304/316 stainless steel screws offer lasting anti-corrosion and anti-loose performance to cut maintenance costs.
Heavy tubular racks, treadmills and weight benches use 304 stainless hex flange bolts to withstand impact vibration.
Allen button head stainless screws secure backrest regulators and height adjusters.
ST stainless tapping screws fasten motor housings and foam brackets without staining.
316 stainless carriage bolts resist rain and chloride for long outdoor service life in public parks.
Knurled stainless thumb screws for bench angle quick adjustment without tools.
