Multiquip 5133 Flat Head Bolt

The Multiquip 5133 Flat Head Bolt is a genuine OEM fastener used across a wide range of Multiquip equipment families, including concrete pumps such as the LS300GK and LS300G, power buggies including the WBH-16, WBH-16E, WBH-21EF, and WTB-16 series, ride-on rollers including the AR13D, AR13H, AR13HC, AR14H, and R2000H, walk-behind trowels in the B Series, Essick EM12M Series mixers, and Mayco pump models including the C30HDZ and LS600P. As a genuine OEM component, the 5133 is produced to Multiquip's exact material and dimensional specifications, ensuring it threads and seats correctly wherever it is called out in the assembly. Sourcing the correct fastener by part number matters — an incorrectly spec'd bolt can compromise joint integrity across structural, mechanical, and fluid-system connections. DHS Equipment stocks the Multiquip 5133 as a direct OEM replacement ready to fulfill your service or repair order.

Key Features

• Genuine OEM Material Spec — Manufactured to Multiquip's exact hardness grade and thread specification, ensuring consistent clamp load and seating depth across every application.
• Flush-Mount Head Design — The flat head profile seats flush with or below the mating surface, maintaining clearance in tight assemblies where a protruding head would interfere with adjacent components.
• Broad Cross-Family Fitment — Confirmed fit across concrete pumps (LS300GK, LS300G, LS300P, LS600P), power buggies (WBH-16, WBH-21EF, WTB-16 series), ride-on rollers (AR13D, AR13H, AR14H, R2000H), walk-behind trowels, and Essick mixers.
• Structural Reliability — A correctly installed fastener maintains joint preload through vibration and load cycling; a worn, stripped, or wrong-spec bolt risks loosening, misalignment, or component separation during operation.
• Direct OEM Drop-In — Same thread pitch, shank diameter, head angle, and drive type as the original, so it installs with standard tooling and torques to spec without rework.

A flat head bolt is a threaded fastener with a countersunk, conical underside that allows the head to sit flush with — or recessed into — the mating surface when fully tightened. This profile is used in applications where a raised bolt head would create interference with moving parts, mating surfaces, or enclosures. Flat head bolts carry both tensile and shear loads depending on the joint design, and they are commonly found securing panels, covers, housings, and structural connections throughout heavy equipment. When a flat head bolt is missing, stripped, or substituted with an incorrect grade or head type, the joint can lose clamp force, allow movement, or fail to maintain a flush surface — any of which can affect the function and safety of the assembly it holds together.
