The Multiquip 2116 HHC Screw 3/8-16 X 4.75 is a genuine OEM fastener designed for Whiteman ride-on power trowels and flat saw equipment, including the STX55, HTX44, and SP2S20H series. As a direct OEM replacement, part 2116 meets the original engineering specifications for thread pitch, length, and head geometry — ensuring a correct, secure fit where it counts. This screw is stocked by DHS Equipment as an authorized Multiquip parts source, so you can be confident you are ordering the right hardware for your machine. Verify fitment against your model code before ordering to confirm compatibility.
Key Features
- Genuine OEM Hardware Spec: — Manufactured to the original 3/8-16 thread specification and 4.75-inch length, matching the exact fastener Multiquip specifies for these assemblies.
- Hex Head Cap Design: — The HHC (hex head cap) profile seats flush and accepts standard wrench and socket tooling for straightforward installation and removal in the field.
- Broad Trowel and Saw Compatibility: — Confirmed fitment across STX55J6, STX55Y6, HTX44Y4, HTX44Y5, HTX44K4, HTX44K5, HTN, and SP2S20H models, covering a wide range of hydrostatic ride-on trowels and flat saw configurations.
- Structural Integrity Where It Matters: — A stretched, stripped, or incorrect-length fastener in a trowel or saw assembly can compromise component alignment and cause accelerated wear on mating parts; replacing with the correct OEM screw restores proper clamping force.
- Critical Fastener Safety: — On rotating equipment such as ride-on trowels and power saws, fastener integrity is a safety-critical factor; using the specified OEM hardware ensures the assembly performs as designed under operational loads.
A hex head cap screw is a structural fastener used to clamp machine components together under controlled torque, maintaining precise alignment and preventing movement between parts during operation. On ride-on power trowels, fasteners of this type are commonly found securing gearbox housings, blade pan assemblies, and structural frame connections where vibration and cyclic loading place constant stress on the joint. When a fastener fails — through stripping, fatigue fracture, or substitution with an incorrect size — the resulting looseness can damage bores, distort mating surfaces, and create unsafe operating conditions that go unnoticed until a more costly failure occurs.
