2X Hex Flanged Bolt & Nut Set 19M7775 & 14M7303 Compatible with John Deere Mower Tractor Batteries TY23017 TY25220 TY25221 TY25221A TY28578 Stainless Steel Battery Terminal Bolt Screw & Nut

What It Is

This is a set of two stainless steel hex flange bolts and matching nuts (models 19M7775 & 14M7303) designed to replace the battery terminal fasteners on John Deere lawn mowers and tractors. It secures battery cables to the battery posts, ensuring a reliable electrical connection.

Fitment & Compatibility

Before buying, confirm your machine uses M6 x 1.0 thread bolts (these are metric). The set replaces OEM parts TY23017, TY25220, TY25221, TY25221A, and TY28578. It fits most John Deere models with side-post or top-post battery terminals, including L, LA, X, Z, and D series lawn tractors and zero-turn mowers. Check your battery terminal type – this set is for threaded studs or J-bolt-style connections, not for universal post adapters. If your battery uses a different thread pitch (e.g., 5/16″-18), this will not fit.

Key Things to Know

• Stainless steel resists corrosion better than standard plated steel, but is softer – avoid overtightening (torque to ~4-6 ft-lb max).
• Installation is tool-free if you have a 10mm socket or wrench – no special skills needed.
• Common gotcha: The flange bolts may be too long for shallow battery terminals – test fit before tightening to avoid bottoming out.
• Not a complete battery hardware kit – you get only two bolts and two nuts; no washers or cable clamps included.

Should You Buy It

Yes, if you need a corrosion-resistant, direct OEM replacement for John Deere battery terminal bolts on a compatible model. It’s a cheap, quick fix for loose or rusted terminals. Skip if your battery uses non-metric threads or if you need a full terminal repair kit.
