Key Features
- Grade 8 Strength Rating — manufactured to Grade 8 specification, delivering the tensile strength and hardness required for high-stress fastener applications on early entry concrete saws.
- Correct Thread Form and Length — 7/16-14 UNC thread and 1-1/2 inch length match the OEM specification exactly, seating flush and threading true without modification.
- Genuine Husqvarna OEM Quality — produced to Husqvarna's original engineering standards, ensuring consistent torque performance and resistance to loosening under machine vibration.
- Direct Fitment for Soff-Cut Early Entry Saws — confirmed fit for the Soff-Cut2000 and Soff-Cut4000, making it straightforward to identify and install the correct fastener during service or repair.
- Structural Integrity You Can Count On — using the correct grade and size bolt in critical assembly points prevents joint failure, misalignment, and component damage that an incorrect fastener can cause.
Hex bolts are structural fasteners used to clamp, secure, and align critical components throughout a machine's assembly. The Grade 8 designation indicates a high-strength bolt capable of withstanding significant clamping loads and the sustained vibration generated during early entry concrete cutting. Using an incorrect grade or improperly sized fastener in these positions can result in joint loosening, component shift, or fastener failure — each of which compromises both cut quality and operator safety. Replacing a worn or damaged bolt with the correct OEM specification part restores the integrity of the assembly and ensures the machine performs as designed.
