Compatibility & fitment guide

How to identify the correct unit: locate the reference number stamped on your original component or in the vehicle parts catalogue, then cross-check it against the number below before ordering. Trim and market variants exist for many applications, so the short check is worth the minute before checkout.

How to identify & confirm fitment in 4 steps

1. Locate the OE / reference number on your old part or in the vehicle parts catalogue.
2. Match it to HR-194A shown on this page.
3. Send your VIN and engine code plate so our team runs an exact-fit check.
4. Receive fitment confirmation before we dispatch your order.

Cross-reference coverage for bolt fitment is listed above; confirm your VIN before ordering.

What this part is

The Bolt is supplied under the Vidishi Auto brand as a compatible aftermarket replacement. It targets universal applications and is referenced by HR-194A. ISO 898-1 property classes for steel bolts are 4.6, 5.8, 8.8, 10.9, 12.9; an 8.8 bolt has 800 MPa UTS and 640 MPa proof strength (first digit x100 = UTS MPa, product x10 = proof). Grade 8.8 hex flange bolts (DIN 6921) are used in automotive, machinery and construction; the integral flange distributes load and reduces vibration loosening, removing the need for a washer. SAE J429 Grade 5 (~827 MPa UTS) is roughly equivalent to ISO 8.8 and Grade 8 (~1034 MPa) to ISO 10.9; radial head marks identify the SAE grade.

Build & materials

Built to the original equipment drawing, the Bolt uses Aluminum Alloy and follows the same inspection checkpoints as the reference sample. Tolerances that affect installation are held to the drawing rather than adjusted on the bench.

• Aluminum Alloy construction for daily and workshop use.
• Surface treated to resist corrosion in road and workshop conditions.
• Dimensional check against the reference sample before packing.

Material and build choices answer the most common bolt replacement and bolt guide questions from workshop buyers.

Where it fits

Suitable for the applications listed in the fitment block. The fitment block above lists the markets and model families this reference is stocked for, so buyers can match demand without re-checking every listing.

Engineering notes

• Torque-to-yield (TTY) bolts are typically single-use; cylinder head and conrod bolts stretch into the plastic range via torque-angle, and reuse does not guarantee specified preload.
• A typical passenger vehicle contains 2,000-3,500 fasteners; a structural joint targets ~70-80% proof, e.g. ~55 kN clamp force at ~67 Nm for an M10x1.5 10.9 bolt (K=0.15).
• Bolt is supplied under the Yamaha, jingke brand as a compatible aftermarket replacement referenced by Yamaha, jingke.
• Origin: Fujian, China; shipped from China, Dongguan in export cartons.
• Minimum order quantity: 1 piece per order for distributors.
• Stainless automotive grades are A2-70 (304 SS, 700 MPa UTS) and A4-80 (316L SS, 800 MPa UTS); stainless-on-stainless thread engagement risks galling/cold welding without anti-seize.
• Roughly 90%+ of automotive fasteners by count are carbon/alloy steel heat-treated to 8.8/10.9/12.9; high-strength 10.9+ need de-embrittlement baking after electroplating to avoid hydrogen embrittlement.

• Pre-dispatch checks: Aluminum Alloy construction is verified against the reference sample before packing.

Workshop teams comparing bolt nut hardware, bolts and nuts and bolt croppers receive the pre-dispatch checklist with the quotation.

• Surface treatments are near-universal: zinc electroplating (5-12 µm), zinc flake (Dacromet, Geomet), phosphate-and-oil, or organic coatings for corrosion protection and friction control.

Installation and service notes for aftermarket bolt for ruger american gen 2, bolt cross reference and best bolt for aftermarket are confirmed by our technical team before dispatch.

• Fatigue dominates in suspension and engine joints; rolled threads improve fatigue life 30-50% over cut threads, and preload should target 70-80% of proof strength.

Workshop teams comparing rocker arm, tillot son and hex flange bolt vibration resistant receive the pre-dispatch checklist with the quotation.
