The Multiquip EM101 Hex Bolt 5/16-18X1 1/2 is a genuine OEM fastener designed for the C30HD concrete pump. As a direct OEM replacement, this bolt is manufactured to the exact thread pitch, diameter, and length required for proper assembly and secure torque retention on C30HD equipment. Multiquip OEM fasteners are held to the same standards as the original hardware installed at the factory, ensuring correct clamping force and thread engagement every time.
Key Features
- OEM Thread Accuracy — Manufactured to 5/16-18 UNC thread specification, matching the original fastener's pitch and engagement depth for a secure, rattle-free connection.
- Correct Length for Direct Installation — At 1 1/2 inches, this bolt installs without shimming or substitution, seating flush to the designed clamping depth on C30HD assemblies.
- Confirmed C30HD Fitment — Sourced and verified for Mayco C30HD concrete pump applications, eliminating guesswork when ordering replacement hardware.
- Structural Integrity Under Load — Proper-grade OEM fasteners maintain joint integrity during the high-vibration operating cycles common to concrete pump equipment; undersized or incorrect bolts can back out or shear under load.
- Genuine Multiquip OEM Part — Supplied under Multiquip part number EM101, ensuring you receive the same hardware specification used in original equipment assembly.
A hex bolt may seem like a simple component, but in concrete pump equipment, fastener grade, thread specification, and length are critical to maintaining safe and secure assembly of covers, brackets, housings, and mechanical sub-assemblies. The EM101 Hex Bolt 5/16-18X1 1/2 ensures the correct clamping load is applied across the joint it secures. Using an incorrect bolt — wrong thread pitch, insufficient length, or lower tensile grade — can result in joint loosening, component misalignment, or hardware failure during operation, which can cause unplanned downtime or damage to surrounding components.
