The root diameter is the diameter of the unthreaded portion of the lag bolt, and can typically be found printed on the bolt. Pilot holes help prevent the wood from splitting and make it easier to drive the bolt in. Web check your chart and slide over the corresponding lag screw size as in the row that lines up. There are a number of variables that may change the required pilot hole dimensions including: For softwood, the pilot hole sizes can be 40% to 70% of the shank diameter for wood with g≤0.5;
The easiest of these to address is wood type. Get your free downloadable chart of commonly accepted pilot hole sizes here. The vibration is apt to crumble the edges of the hole in the particleboard. Web a pilot hole size for lag bolts can vary depending on the diameter and length of the bolt. Web i found many charts that say the pilot hole size for a 5/8 lag is 13/32.
Hold the drill bit up in front of the screw. Web drilling a pilot hole and need to know what drill bit size to use? From there, you’ll be able to identify the head height, head width, and thread dimensions of the lag screw, with their subsequent minimum (min.) and maximum (max.) limits. The thread itself is 1/2”. I’d still go with the shank (minor diameter) as steve said.

Lag Screws Are Fully Threaded And Come With Coarse Threads That Are Widely Separated:
Soft wood 40% to 70% of the shank diameter for wood with g ≤ 0.5. Generally, the pilot hole size should match the root diameter of the threaded portion of the bolt. In some cases, even that is very snug. The vibration is apt to crumble the edges of the hole in the particleboard.
Choose A Drill Bit Slightly Smaller Than The Lag Bolt's Diameter.
The easiest of these to address is wood type. Pilot hole size can range as follows: From there, you’ll be able to identify the head height, head width, and thread dimensions of the lag screw, with their subsequent minimum (min.) and maximum (max.) limits. Variables such as wood type, bolt length and bolt diameter all factor into ideal pilot hole sizes.
The Root Diameter Is The Diameter Of The Unthreaded Portion Of The Lag Bolt, And Can Typically Be Found Printed On The Bolt.
When the shank disappears behind the drill bit and all you see is threads then you have the right pilot hole size. The pilot hole will nestle the screw, making sure it remains securely in place.
