The Husqvarna 505687701 Hex Head Bolt 5/16-18 x 2 Grade 8 is a genuine OEM fastener designed for the Soff-Cut4000, Soff-Cut150, and Soff-Cut150D early entry saws. As a Grade 8 bolt, this component meets the high-strength requirements of Husqvarna's early entry saw assemblies, ensuring a secure, properly torqued connection wherever it is installed. DHS Equipment supplies this part to help keep your equipment performing at the level Husqvarna intended.
Key Features
- Grade 8 High-Strength Construction — Manufactured to Grade 8 specifications, this bolt delivers the tensile strength and hardness required for demanding fastener positions on green-concrete cutting equipment.
- Genuine OEM Specification — A direct Husqvarna OEM part, matched to the exact thread pitch (5/16-18) and length (2 in.) called out in the Soff-Cut parts diagram — no sizing guesswork required.
- Fits Soff-Cut Early Entry Saws — Confirmed fitment for the Soff-Cut4000, Soff-Cut150, and Soff-Cut150D early entry saws. Cross-reference part number 505687701 against your machine's parts diagram before ordering.
- Maintains Structural Integrity — A correctly specified bolt holds critical assemblies firm under the vibration and load of early-entry concrete cutting; an undersized or incorrect-grade substitute risks joint loosening and component damage.
- Direct Drop-In Replacement — Threads and dimensions match the OEM specification exactly, so this bolt installs into the original fastener position without modification.
A hex head bolt of this grade and size serves as a primary structural fastener within the Soff-Cut early entry saw assembly. Grade 8 fasteners are specified wherever high clamping force and resistance to shear or vibration-induced loosening are essential — conditions common in walk-behind concrete cutting applications. When a fastener in this position is worn, damaged, or replaced with an incorrect grade, joint integrity is compromised, which can affect blade alignment, guard retention, or the stability of key drive components.
