Capscrew Markings and Torque Values

Caution: When replacing capscrews, always use a capscrew of the same measurement and strength as

the capscrew being replaced. Using incorrect capscrews can result in engine damage.

SAE capscrews are graded according to the strength of the capscrew. They are marked on the head so the correct

strength and torque value are known.

The table below lists the capscrew markings and the correct value for the capscrew. SAE capscrews are identified

by:

U.S. Customary (5/16 X 18 X 1 1/2)

5/16 18 1 1/2

Major Number Length

Thread Threads in

Diameter per Inch Inches

in Inches

Notes:

1. Always use the torque values listed in the following table when specific torque values are not available.

2. Do not use the torque values in place of those specified in other sections of this manual. It is important to use

the correct torque values for SAE grade 5 and 8 capscrews.

3. The torque values in the table are based on the use of lubricated threads.
