ASME Swing-Bolt, Dimension: 5.13 in Swing-Bolt Length

Betts offers a variety of ASME swing-bolts for the full opening manhole product line. All ASME swing-bolts are a solid 1-piece design made from 17-4 PH stainless steel with 5/8-11 UNC threads. Wing-nuts are 304 stainless steel. Wing-nut includes a staked-on bearing washer for decreased wear and a retention e-clip is included on top of swing-bolt to keep the wing-nut from accidentally unthreading off of the swing-bolt while opening manhole. Assemblies ending in 002 include swing-bolt pin (4463SL) and 1/8 in coil pin (9Q8605). Please note: older style swing-bolts have a larger coil pin hole diameter; therefore, specify the 002 kit to ensure the necessary replacement components are received. Swing-bolt/wing-nut assemblies will last longer if properly maintained. Stainless steel on stainless steel threads are challenging and threads must be kept clean and lubricated with anti-seize compound, and never hit wing-nuts with a hammer. Use proper wing-nut tools 7611SL, 6443SS or 6469SL with a maximum torque of 45 ft lb. The sealed wing-nut option offers a solid top-plate to protect the threads from water or debris and also includes a grease fitting for preventive maintenance.ASME Swing-Bolt, Dimension: 5.13 in Swing-Bolt Length
