How to fit a garden gate latch without splitting the stile

Updated: October 2026

You have a wooden garden gate, a drill, and either a ring latch or a slide bolt on the bench. The spindle hole and the surface bolt are different jobs. Drilling a through-hole from one face until the bit bursts out is how the far stile splits. The [gate latch comparison](/hub/fencing-and-wire/gate-latch) is the product table. Peter F. used fitting notes from Lawsons, Woodworkers UK, and Suffolk Farm Fencing, plus the listing limits on file. These latches were not fitted in a workshop.

Measure before you drill

Close the leaf and look at the gap before you mark a hole. The guides used here put about 40 to 50 mm of the bar onto the post. Woodworkers UK allows about 50 mm of bar past the stile. If the gap is wider than the bar can cover, no bit size will fix it. A ring bar sits where you can lift it from both sides once the spindle is through. A slide bolt sits on the face you will use and never needs a hole through the stile. Keypak B005347XTO states an 8 cm spindle and leaves the thickness field blank, so do not borrow a 75 mm maximum from another brand.

Ring latch: spindle, then screws

Lawsons and Suffolk Farm Fencing describe a 12 mm spindle hole and 40 to 50 mm of overlap. Woodworkers UK, fitting a 10 mm spindle, uses a 16 mm spur bit, stops when the spur shows, and finishes from the other side. Those are not one universal bit. Keypak states an 8 cm spindle length, not a diameter. Size the hole so your spindle turns, and drill from both faces. A hole driven through from the garden side is the mistake that splits the street face. Woodworkers UK uses a 3 or 4 mm pilot for the rose screws. If the spindle stands proud, cut it.

Slide bolt: no hole through the stile

A slide bolt is a surface fit. Woodworkers UK marks the bolt on the face, pre-drills at about 3 mm, and offers the keep while the gate is shut. DIY Doctor drives one screw first so you can level it, with pilots of about 2 to 3 mm. Lawsons’ tower-bolt order is the same idea: fix the bolt, then the staple, with the bolt shot. You are lining a bar up with a socket, not boring a spindle. SAYAYO B08JV2B4WL conflicts between 160 mm and 150 mm. ASelected says 355 mm in the title and 1 cm on a dimensions line. FOBOZONE lists screws at 8 x 25 mm and 8 x 15 mm, and a review describes heads shearing.

When the screws or the leaf say stop

Stop when a screw head starts to round or the shank shears. Driving on buries a broken head in the stile. Review notes mention sheared heads on the FOBOZONE bolt, the Keypak auto latch, the Weielt catch, and the SAYAYO bolt that does not state 304. That is a review theme, not a measured torque. Back the screw out and use a fixing that matches the timber. The Weielt cable is not a spindle. One reviewer got it through a 4 inch post, which is one report. Choosing the mechanism before you mark anything is ring latch or slide bolt.

Common questions

How big a hole does a ring-latch spindle need?
Lawsons and Suffolk Farm Fencing describe a 12 mm hole. Woodworkers UK used a 16 mm spur bit for a 10 mm spindle, so the bit was larger than that spindle, not a universal 16 mm for every latch. Keypak B005347XTO states an 8 cm spindle length and does not state a diameter, and its thickness field is blank.
How much should the latch bar overlap the post?
About 40 to 50 mm of bar onto the frame is the figure Lawsons and Suffolk Farm Fencing use. Woodworkers UK allows about 50 mm of bar past the stile, and Gates and Fences UK is in the same range. Hold the leaf shut and measure your gap before you mark the hole. If the bar cannot cover that gap, overlap advice will not close it.
Why drill the spindle from both sides?
A bit driven through from one face tears the fibres as it exits, and that is how the far stile splits. Woodworkers UK stops when the spur shows, then finishes from the other side. The same care applies if you are following the 12 mm method: do not push the bit out in one pass. A surface bolt does not need this hole at all.
What if the spindle is longer than the gate is thick?
Cut it so it does not stand proud. Lawsons says to shorten a spindle that is too long. Suffolk Farm Fencing notes that the spindle may need cutting when the leaf is under 4 inches thick. Keypak states 8 cm and does not state a maximum gate thickness, so you compare that spindle with your stile rather than with another brand’s 75 mm limit.
How is a slide bolt fitted differently?
You fix it on the face. Mark the bolt, drive one screw so you can level it, pilot the rest at about 2 to 3 mm as DIY Doctor describes, or about 3 mm as Woodworkers UK’s padbolt page describes, then offer the keep with the gate shut and the bolt shot. There is no spindle and no through-hole in the stile.
What should you do when the supplied screws start to round?
Stop. A head that is rounding or shearing will snap if you keep driving, and the reviews in this set already describe that on FOBOZONE screws, among others. Back the screw out. The pilots in the public guides are 3 mm, or 3 to 4 mm on a ring rose, for the kits those pages describe. They are not a specified pilot for every screw in these packs.
When should a fitter take over?
When the leaf can drop off the hinges, the posts move, or the boundary is listed. A latch guide assumes a gate that already hangs and a frame that can take screws. Children, pets, and seller lines about them are a different page: child proof garden gate latch.
