Huaduo Chicago Screws Hex Socket Barrel Bolts and Nuts

Size：M6-M20

Length：10mm to 300mm

Socket barrel nuts (Hex head sleeve nuts) host a hexagonal recess in the head. These socket head barrel nuts are installed using a hex wrench or insert bit.

This, together with the relatively large head diameter, provides higher resistance to cam-out and they can be used with power drivers enabling faster installation and higher torque to be achieved.

PRODUCT DETAILS:

Barrel Nuts are internally threaded fasteners which when used in conjunction with a male threaded fastener can be used to clamp two ore more components together. The heads of the countersunk nuts are designed to fit flush with the surface of the fastened material making them popular with carpentry, cabinetry and DIY projects.

How to Use Socket Barrel Nuts and Bolts and Determine the Hex L Key Size？

Installation Process:

—Aligning the Components:
Ensure that the parts being fastened are properly aligned with the holes drilled for the Socket Barrel Nuts and Bolts.

—Inserting the Barrel Nut:
Insert the barrel nut into the pre-drilled hole. The slot of the barrel nut should align with the bolt hole. Barrel nuts typically have a flat head to prevent rotation during tightening.

—Inserting the Barrel Bolt:
Insert the hex socket bolt through the opposite hole, threading it into the barrel nut. Ensure the bolt is of appropriate length so it fully engages with the barrel nut threads without protruding excessively.

—Tightening:
Use a Hex L Key (Allen wrench) to tighten the bolt. Insert the Hex L Key into the socket head of the bolt and turn clockwise to tighten. Ensure both the bolt and the barrel nut are securely fastened.

—Determining the Hex L Key Size:
The size of the Hex L Key needed corresponds to the size of the hex socket in the bolt head. Here are common hex socket bolt sizes and their corresponding Hex L Key sizes:
M5 bolt: 4mm Hex L Key
M6 bolt: 5mm Hex L Key
M8 bolt: 6mm Hex L Key
M10 bolt: 8mm Hex L Key

These sizes ensure that you have the appropriate tool for applying the necessary torque without damaging the bolt head.
