Multiquip 5277 Screw Hex Head Cap 1/4-20 x 1-1/2

The Multiquip 5277 is a genuine OEM Screw Hex Head Cap 1/4-20 x 1-1/2 used across a wide range of Multiquip and Whiteman equipment, including ride-on power trowels, pavement saws, masonry saws, walk-behind trowels, roller screeds, and more. As a genuine OEM fastener, it is manufactured to the exact thread specification, head geometry, and material grade called out in the original equipment bill of materials. This screw fits an extensive list of models — including the HHN, HTX, STX, HTN, SP, MP, and MS series — making it a high-volume service item worth stocking for fleets running multiple Multiquip machine types. Sourcing part number 5277 directly from an authorized Multiquip distributor ensures you receive the correct fastener rather than a dimensional approximation.

Key Features

• Correct Thread Form and Pitch: — Cut to 1/4-20 UNC thread standard with a 1-1/2 in. grip length, matching the original fastener specification for proper clamp load and engagement depth.
• Genuine OEM Part: — Manufactured to Multiquip's material and hardness grade requirements, so the fastener performs consistently in the structural and panel joints where it is specified.
• Broad Cross-Family Fitment: — A single part number used across ride-on trowels (HHN, HTX, STX, HTN), pavement saws (SP30 and SP60 series), masonry saws (MP and MS series), walk-behind trowels, roller screeds, and DEF tank assemblies.
• Drop-In Service Replacement: — Hex head drive pattern is compatible with standard 7/16 in. wrenches and sockets already on the service truck, with no special tooling required for installation.
• Prevents Fastener-Related Failures: — A stripped, corroded, or under-spec screw in a guard, panel, or structural mount can allow components to shift or come loose under vibration. Using the correct OEM fastener maintains joint integrity through normal machine operation.

A hex head cap screw is a fully threaded or partially threaded fastener with a six-sided head designed to be driven by a wrench or socket. In construction equipment, these screws secure guards, covers, mounting brackets, and structural members throughout the machine. The 1/4-20 x 1-1/2 designation describes the major thread diameter (1/4 in.), thread pitch (20 threads per inch), and nominal grip length (1-1/2 in.) — all of which must match the tapped hole or nut specification exactly to develop the correct clamping force. When a cap screw fails through corrosion, cross-threading, or fatigue, the joint it holds can loosen, creating noise, misalignment, or safety concerns depending on where in the machine it is located.
