Description

OEM-grade bolt‑on fasteners used to secure sickle or knifehead sections on agricultural equipment—ideal for mowers, mower-conditioners, combines, and harvesters.

Key Features

  • Bolt Size & Quantity:
    • Includes 15 pieces of 1″ long, 12‑24 thread bolts with matching lock nuts.
  • Construction:
    • Heavy-duty steel bolts and lock‑nuts—often SAE Grade 5 or better—ensure a secure and vibration-resistant hold under tough operating conditions. Made in the USA.
  • Compatibility:
    • Specifically Kondex 904‑513, but cross‑referenced to other OEM codes like John Deere 904‑501. Easily fits standard knifehead assemblies using 1″ bolts.

Typical Applications

  • Secure Knifehead Sections:
    • Bolts fasten the knife section to the head assembly on sickle bar mowers and combine headers.
  • Field Reliability:
    • Lock-nut design resists vibrations, preventing loosening during heavy use.
  • Maintenance Convenience:
    • Sold in a 15-piece pack—enough to replace fasteners on 3–5 sections (typically 3–4 bolts per section).
