CAT Genuine High-Strength Fastening Bolts with Precision Thread Design for C15 C18 Excavator Engine

CAT Genuine Parts For 451-8195 4518195 bolts CAT C15 C18 Excavator Engine Parts

Specification

Description

Part Number: 451-8195 / 4518195, named ROD-ALT high-strength fastening bolt. It is a standard fastening component matching CAT C15 and C18 excavator engines. Each sealed package contains 5 bolts. Manufactured with standardized production procedures, each bolt is wrapped with protective mesh to prevent damage. This fastener is widely applied to assemble and repair key components including engine block, cylinder head and pipeline of C15 & C18 construction excavator engines, serving as a regular replacement part for engine overhaul and routine maintenance to fit heavy-duty construction operation. All goods are well packed with clear labels for easy storage, and precise dimension ensures seamless installation. Warranty terms can be discussed and confirmed.

Advantage

Perfect Matching: Produced strictly according to original assembly parameters of CAT C15 and C18 engines. The thread, length and size fit original equipment perfectly with no grinding or modification required for quick installation.
Complete Original Package: Sold in packs of 5 pieces. The protective mesh effectively protects screw threads against collision and abrasion during transit and storage. Clear packaging marks support easy inventory counting and classification.
Wide Compatibility: Compatible with multiple excavator models powered by C15 and C18 engines. One bolt fits multiple mounting positions, lowering stocking pressure for repair workshops.
Stable Supply: In sufficient stock with short replenishment lead time, meeting urgent field repair and bulk engine overhaul demands efficiently.

Performance

Premium Raw Material: Made of fine-grain alloy steel with strict heat treatment procedures. Its tensile strength and shear resistance meet top-grade fastener standards, resisting breakage and deformation under long-term high temperature, vibration and heavy loads inside engines.
Precise Thread Design: Adopts precision rolled thread with uniform texture. It provides stable clamping force after tightening, effectively avoiding thread slipping and loosening caused by long-period operation, reducing risks of oil leakage and structural looseness.
Strong Environmental Resistance: Equipped with professional anti-corrosion coating. It features great rust resistance, oil resistance and high-temperature tolerance, adapting to harsh engine bay conditions with high heat, oil contamination and dust to resist aging and corrosion.
Stable Mechanical Performance: Balanced stress performance under frequent temperature changes. Fastening force will not decline under continuous vibration from engine start-stop cycles, extending service life and cutting machine downtime for maintenance.
