Multiquip 36720 Screw Hex Head Flange 5/16-18 x 3/4 GR5

The Multiquip 36720 is a genuine OEM Screw Hex Head Flange 5/16-18 x 3/4 GR5 designed for a wide range of Multiquip and Whiteman equipment including SP-series flat saws, PRX and HTX ride-on power trowels, STX ride-on power trowels, WSHE vibratory screeds, WRS roller screeds, and LT6K towable light towers. As a genuine OEM component, it is manufactured to the exact dimensions and grade specification called out in the original equipment design. Verified fitment includes the SP118, SP1G, SP2S20H, PRX, HTXD6i, STXD6i, HHNG5, JWN24HTCSL, WRSPUDF, WRS5200, WRS5200DFPU, LT6K, LT6KV, and WSHE-A series, among others. Ordering by part number 36720 ensures you receive the correct fastener grade and thread specification every time.

Key Features

• Grade 5 Tensile Strength — The GR5 rating delivers the shear and tensile load capacity required for structural and mechanical mounting points on heavy-use construction equipment.
• Flanged Head Design — The integrated flange distributes clamping load across a wider bearing surface, reducing the need for a separate flat washer and maintaining consistent joint preload.
• Exact OEM Thread Specification — Cut to a 5/16-18 UNC thread pitch and 3/4-inch grip length, this fastener installs directly into OEM-tapped holes without rethreading or modification.
• Broad Cross-Equipment Fitment — Confirmed for SP-series flat saws, PRX and HTX/STX ride-on trowels, WSHE vibratory screeds, WRS roller screeds, and LT6K light towers — one part number covering multiple Multiquip product families.
• Genuine OEM Sourcing — Supplied as an authorized Multiquip OEM part, meaning the material grade, plating, and dimensional tolerances match the original fastener specification exactly.

A hex head flange screw serves as a load-bearing fastener that clamps two or more components together at a fixed torque value. The flange beneath the head acts as a built-in washer, spreading the clamp force over a larger area to prevent pull-through and surface damage on softer substrates. Using the correct grade and thread specification matters because under-spec fasteners can stretch, loosen under vibration, or shear under load — any of which can lead to component misalignment, accelerated wear on adjoining parts, or unexpected mechanical failure during operation. Replacing a worn or damaged fastener with the genuine Multiquip 36720 restores the joint to its original engineered clamping specification.
