The Multiquip 913821 is a genuine OEM Hex Tap Screw 1/2-13 x 2 Grade 5 Plated designed for GRD5 series equipment. As a factory-sourced fastener, it meets the exact material grade and thread specification called out in the original Multiquip parts documentation. This screw threads directly into place with no modification, keeping your assembly properly torqued and secure. DHS Equipment stocks this part to get you back on the job without guesswork on fitment.
Key Features
- Grade 5 Structural Rating — Medium-carbon steel construction meets Grade 5 tensile and proof-load requirements, delivering the clamping force this fastener position demands.
- Zinc-Plated Corrosion Resistance — Electroplated finish protects the fastener against moisture and oxidation, extending service life in outdoor and high-humidity construction environments.
- Correct 1/2-13 Thread Form — UNC 1/2-13 thread pitch matches the tapped hole exactly, preventing cross-threading and ensuring full thread engagement at installation.
- Genuine OEM Sourcing — Supplied directly through the Multiquip parts network under part number 913821, so you receive the identical fastener specified at the time of manufacture.
- GRD5 Equipment Compatibility — Verified fitment for GRD5 series machines, eliminating the uncertainty of sourcing a hardware-store substitute that may not match the required grade or plating spec.
A hex tap screw is a self-tapping fastener designed to cut or form its own threads as it is driven into a pre-drilled hole, creating a secure threaded connection without requiring a separate nut. The Grade 5 designation confirms the fastener has been manufactured to a defined minimum tensile strength, making it suitable for structural and load-bearing attachment points on equipment assemblies. Using a fastener of the incorrect grade or thread pitch in these positions can result in joint slippage, stripped threads, or hardware failure under vibration — all of which compromise both machine integrity and operator safety.
