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).
