Zoro Select M24-3.00 Socket Head Cap Screw

This Zoro Select fastener is a metric socket head cap screw made from alloy steel with a black oxide finish. It features a thread size of M24-3.00 and an overall fastener length of 130 mm. The drive type is socket with a 19 mm drive size. It conforms to dimensional standard ASME B 18.3.

Suitability and limitations

This screw suits applications requiring a standard head height of 24 mm and head diameter of 36 mm. The partially threaded design provides a minimum thread length of 60 mm. Builders needing a fully threaded shaft or a different drive style should look at other fastener types. Countersunk or flanged head requirements are not met by this item.

Deciding specification: M24-3.00 thread size

The M24-3.00 thread size is the single specification that determines compatibility with the mating nut or tapped hole. Verify that the required pitch matches 3.00 mm before purchase. An incorrect thread pitch will prevent proper engagement and clamping force. All other dimensions are secondary to this match.

Questions about this item

What does the ASME B18.3 standard specify for this M24-3.00 screw?

It defines the 36 mm head diameter, 24 mm head height, and 19 mm socket drive dimensions for this alloy steel fastener.

What clearance is needed for the 36 mm head and 19 mm socket drive?

A 36 mm diameter bore fits the head, while a 19 mm hex bit requires enough depth to engage the 24 mm tall head fully.

How do you install this 130 mm partially threaded screw without bottoming out the 60 mm thread?

Drive the 19 mm socket until the head seats; the 60 mm thread length stops turning before the 130 mm shank hits the hole bottom.
