The Multiquip 492491 1/2" x 1" NC Bolt Set is a genuine OEM fastener set designed for MC-series concrete mixers and LS-series concrete pumps including the MC94P, MC94S, MC64P, MC64S, MC12PH, LS300GK, LS300G, LS300P, LS400, LS500, LS600, LS600P, LS40D, LS40TD, LS50TD, and LS60TD. As a genuine OEM component, this bolt set is manufactured to the exact thread specification and dimensional tolerances Multiquip requires for correct assembly and clamping performance. Sourcing the correct fastener grade and thread pitch matters on high-cycle equipment like concrete mixers and pumps, where loose or mismatched hardware accelerates wear on mating surfaces and can cause structural failure under load. DHS Equipment supplies this part direct, so you get the right hardware the first time.
Key Features
- Correct Thread Form and Grade — NC (National Coarse) thread spec matches the original tapped holes in MC-series mixer and LS-series pump assemblies, ensuring full thread engagement and proper torque retention.
- Genuine OEM Fastener — Manufactured to Multiquip's exact material and dimensional standard, so clamping force and bolt stretch remain within design limits for these machines.
- Broad MC and LS Series Fitment — Compatible across MC94P/S, MC94SK/PK, MC64P/S, MC64SK/PK, MC12PH, LS300GK, LS300G/P, LS400, LS500, LS600/P, LS40D, LS40TD, LS50TD, and LS60TD equipment.
- Prevents Fastener-Induced Damage — Using the correct bolt length and thread pitch eliminates thread stripping, bottom-out conditions, and joint slippage that worn or incorrect hardware can cause on high-vibration concrete equipment.
- Direct Service Replacement — Supplied as a set to support scheduled maintenance, drum replacement, panel re-assembly, or pump housing service without hunting for individual fasteners.
Bolts in this class secure structural and operational joints on concrete mixers and pumps — components that transmit significant torque, vibration, and compressive load during every cycle of use. A correctly specified bolt set maintains joint integrity by achieving the proper preload when torqued, preventing loosening and fretting of the clamped surfaces. When bolts are the wrong length, grade, or thread form, joint preload is compromised, leading to movement, accelerated wear on surrounding components, and potential structural failure — particularly critical on equipment handling dense concrete or hydraulic pressure.
