Overview — Hex Head Cap Screw 110266
110266 is the hex head cap screw used on CUMMINS diesel engines for fastening components in the specified threaded positions, supplied in the original grade and dimensions. We can supply all the original and replacement part numbers listed below, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The cap screw is manufactured to the original thread size, pitch, length and strength grade, with a hex head sized for the correct wrench. The material and heat treatment match the original specification so the screw holds the required clamping load without stretching or yielding. Threads are rolled to the original profile for consistent engagement, and the finish resists corrosion in the engine environment. As an OEM-spec cap screw, it replaces the original fastener without changes to the torque specification or the parts it clamps.
Applicable Models & Applications
This hex head cap screw is used across CUMMINS engine families in the threaded joints specified by the original part number, including component mounting, cover retention, bracket fixing and accessory attachment. The family covers the same fastening duty across a wide range of builds, with the reference numbers 3638713, 4096527, 4096711, 4951606, 4951607, 4951608, 800-3017-76, 800-3017-78, 800-3047-01 and C369571 identifying related variants. Confirm the thread size, length and head style against the screw removed from your engine before ordering.
Maintenance & Replacement
Replace any cap screw that is worn, stretched, corroded or has damaged threads, and never reuse a screw removed under tension if the original procedure specifies new fasteners. Clean the threads of both the screw and the tapped hole, and apply the lubrication and thread locker specified in the manual. Tighten to the correct torque with a calibrated wrench, following the tightening sequence given for multi-fastener joints. Check the fastener during routine service for signs of loosening, especially on components subject to vibration.
