ARP's Rod Bolt Stretch Gauge provides an extremely accurate measurement when the tightening up your conrod fixings, which is always preferable to using a torque wrench. Some very high tensile bolts like Carrillo CARR bolts can be re-used indefinitely provided the stretch is measured and checked against the bolt specification each time.

Measuring the bolt length before tightening and after torque is applied allows you to accurately reach this figure. Accurately reaching a specified torque figure is affected by friction between the threads, the condition of the threads, and the smoothness of the interface between the underside of the bolt head and the connecting rod, the material strength of the bolt, the lubricant used, and the accuracy of the torque wrench being used. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . Les mesures comprennent : diamètre intérieur d'écrous UNC et UNF, diamètre de boulons de dimensions métriques et impériales, longueur de vis à tête ronde, à tête cylindrique, à tête fraisée, de vis d'arrêt, ainsi que de boulons à tête hexagonale ; tableau de référence pour les vis à 6 pans creux.Es eignet sich sowohl für metrische als auch für zöllige Befestigungen und kann auch verwendet werden, um festzustellen, ob ein Mutter UNC- oder UNF-Gewinde hat; das Ausprobieren bei der Auswahl der richtigen Ersatzgröße entfällt. This can also be used to monitor the condition of the bolt when installed, which is particularly useful on a race engine that's regularly apart for check-ups. It's been developed to provide optimum accuracy in determining the correct pre-load of the installed rod bolt.

Messbar sind: Innendurchmesser von Muttern mit UNC- und UNF-Gewinde; Durchmesser von metrischen und zölligen Schrauben; Länge von Rund-, Flach- und Senkschrauben; Gewindestiften und Sechskantschrauben; mit Referenztabelle für Sechskant-Kopfschrauben. For fasteners where the head usually sits above the surface, the measurement is from directly under the head to the end of the fastener. Het is geschikt voor gebruik op zowel metrische als imperiale bevestigingen en kan ook gebruikt worden om te bepalen of een moer UNC of UNF is, waardoor er niet meer geraden hoeft te worden uit het selecteren van de juiste vervangingsmaat.

Ce calibre à lecture facile est en plastique ABS robuste et offre un moyen rapide et facile de mesurer la taille d'écrous, de boulons et de vis. Dieses leicht ablesbare Messgerät ist aus robustem ABS-Kunststoff gefertigt und ermöglicht eine schnelle und einfache Messung der Größe von Muttern, Bolzen und Schrauben. For accurate strain measurement the bolt requires calibration using a tensile test once the gauge is installed. Finance is provided by PayPal Credit (a trading name of PayPal UK Ltd, Whittaker House, Whittaker Avenue, Richmond-Upon-Thames, Surrey, United Kingdom, TW9 1EH). The way of adhering a BTM (bolt strain gauge) differs from a general strain gauge, requiring drilling of the bolt, embedding the strain gauge, and load calibration.

For fasteners that are designed to be countersunk, the measurement is made from the point on the head where the surface of the material is, to the end of the fastener. We are also the UK and European distributor for Aircraft Spruce and Speciality, with whom we have been doing business with for over 25 years. This easy to read gauge is made from tough ABS plastic and provides a quick and easy way to measure the size of nut, bolts, and screws. Accurate tensile force measurement is possible by calibrating the bolt after installing the bolt gauges. The gauge is supplied with a heavy-duty carry case and is ideal for both DIY and professional engine builders.Because this is approximately the same as the Major or Thread diameter the thread diameter measurement can be used for fully threaded bolts. Multifunctional measuring tool for sizing screws, bolts and nuts diameter, coarse and fine-thread checking and length sizing. The thread pitch is the distance between threads expressed in millimetres (measured along the length of the fastener). Das Multifunktions-Messwerkzeug für Muttern, Bolzen und Schrauben hilft dem Anwender bei der Überprüfung von Größen und Gewinden, einschließlich metrischer und angelsächsischer Maße; kein Rätselraten mehr bei der Auswahl der richtigen Größe von Befestigungselementen.
