Multiquip 11090 Socket Head Cap Screw 3/8-16 x 1-1/4 Plated

The Multiquip 11090 is a genuine OEM Socket Head Cap Screw 3/8-16 x 1-1/4 Plated designed for EM12M Series and EM120SM Essick mixers, JTNSW20 and JTNS20 International ride-on power trowels, and JTO Series Whiteman ride-on power trowels. As a genuine OEM fastener, the 11090 meets the exact thread specification, plating grade, and head geometry called out in Multiquip's original assembly designs. Sourcing the correct fastener matters — an incorrect thread pitch or under-rated coating can compromise joint integrity across multiple machine families. Verify your model code against the fitment list before ordering to confirm this is the right screw for your application.

Key Features

• Correct Thread Specification — 3/8-16 UNC thread form and 1-1/4 inch length match the precise engagement depth required at OEM assembly points on Essick mixers and Whiteman ride-on trowels.
• Plated Corrosion Resistance — Zinc plating provides a protective barrier against moisture and surface oxidation, helping the fastener maintain clamping load in outdoor and wet-mix construction environments.
• Socket Head Drive — Internal hex drive allows installation in recessed or tight-clearance locations where a conventional hex head cannot seat, keeping assembly straightforward with standard Allen tooling.
• Broad Cross-Family Fitment — A single OEM part number covers EM12M Series, EM120SM, JTNSW20, JTNS20, and JTO Series equipment, making it a practical stocking fastener across multiple Multiquip machine lines.
• Genuine OEM Part — Sourced directly through Multiquip's OEM supply chain, so thread tolerance, head dimensions, and plating spec are consistent with every other fastener used in the original build.

A socket head cap screw is a high-strength fastener used to clamp components together at specific torque values, typically in locations where precise tightening and a low-profile head are required. The internal hex socket allows the fastener to be driven with an Allen key or hex bit in confined spaces that a standard wrench cannot reach. When a socket head cap screw is worn, stripped, or replaced with an incorrect size, it can result in loose assemblies, accelerated wear on mating components, and potential structural failure at critical joints — making correct specification essential during any service or rebuild procedure.
