The Multiquip 16721 is a genuine OEM Hex Head Cap Screw 3/8-24 x 1-3/4 designed for Whiteman ride-on roller screed models WRS5200DFPU, WRS5200, and WRSPUDF. As a direct OEM replacement, this fastener is manufactured to the exact thread pitch, grip length, and head specification required by Multiquip for these machines. Sourced directly through authorized Multiquip supply channels, part 16721 ensures the correct fit without guesswork or modification. Keep this fastener on hand as a service spare to avoid delays during routine maintenance or field repairs on your roller screed.
Key Features
- Genuine OEM Thread Accuracy — Manufactured to the exact 3/8-24 UNF thread specification, ensuring full thread engagement without cross-threading risk on the screed's threaded receivers.
- Correct Grip Length for This Application — The 1-3/4 inch body length matches the original fastener stack-up on WRS5200 and WRSPUDF assemblies, seating flush without under- or over-clamping.
- Confirmed Fitment for WRS Roller Screed Models — Verified for use on WRS5200DFPU, WRS5200, and WRSPUDF Whiteman ride-on roller screeds.
- Structural Integrity Where It Counts — A properly torqued hex head cap screw maintains critical joint clamping force on the screed frame; a stripped or incorrect fastener can cause component loosening under the vibration loads typical of screed operation.
- Hex Drive for Field Torque Control — The hex head format allows use of standard wrenches or impact tools in the field, enabling accurate torque application and reliable re-use of the fastener joint.
A hex head cap screw is a precision-threaded fastener used to clamp and secure structural or mechanical components together on the machine. On ride-on roller screeds like the WRS5200 series, fasteners like the 16721 hold frame assemblies, mounting brackets, and mechanical subassemblies in alignment under continuous vibration during concrete finishing operations. When a fastener stretches, strips, or is replaced with an incorrect thread pitch or length, it can compromise joint clamping force, accelerate wear on mating threads, and lead to component loosening or misalignment mid-operation. Using the correct OEM specification fastener maintains the integrity of the joint as the machine was originally engineered.
