Overview — Hex Head Screw 136574
136574 is the hex head screw used on CUMMINS diesel engines for fastening components in the specified thread positions, supplied in the original grade and dimensions. We can supply this screw as well as related CUMMINS fasteners, in stock or available on order — welcome to enquire by part number.
Parts Characteristics
The 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 in service. Threads are rolled to the original profile for consistent engagement, and the finish resists corrosion in the engine environment. As an OEM-spec fastener, it replaces the original screw without changes to the torque specification or the parts it clamps.
Applicable Models & Applications
This hex head 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 same screw is commonly shared across multiple engine models and applications, including construction, industrial, generator and marine installations. Confirm the thread size, length and head style against the screw removed from your engine before ordering, and check whether the original joint uses a locking feature such as thread locker or a captive washer.
Maintenance & Replacement
Replace any screw that is worn, stretched, corroded or has damaged threads; never reuse a screw that was removed under tension if the original service procedure specifies new fasteners. When refitting, 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 rather than relying on feel, and follow the tightening sequence given for multi-fastener joints. Check the fastener during routine service for signs of loosening, especially on components subject to vibration.
Price Reference (USD)
The reference price for this Hex Head Screw (136574) is approximately USD 2 – 10 per unit depending on size, grade, quantity and shipping destination. This is a planning estimate only — confirm current pricing and availability with our sales team before ordering.
Value & Service
Fasteners are small parts with big consequences — a wrong grade or thread can strip a casting or loosen under vibration — so we verify 136574 against the original CUMMINS specification and confirm thread, length and grade before dispatch. We stock the screw in bulk and offer quantity pricing for workshops and rebuilders who need fasteners in volume, and orders can be combined with other service parts into one tracked shipment. Our team will confirm the correct part number if you are unsure which screw your joint requires.
