In Detail

Pocket hole joinery is all about making strong joints that are fast and easy to produce with a hidden joint. They are produced using a jig and drilling a hole at an angle into one workpiece. This is then joined to a second workpiece with a hardened steel self-tapping screw.

SPEED – eliminates the need to pre-drill the mating workpiece.

STRENGTH – screw acts as an internal clamp and is stronger than a biscuit, dowel or tenon.

GRIP – constant clamping force combined with today’s glue technology makes for an incredibly strong wood-to-wood bond.

Material: Zinc plated steel screws made to DIN 1.1133

Thread Type: The coarse thread screw suits softwood such as MDF, melamine, plywood and pine.

Head Style: All UJK screws use Torx T20, chosen to provide the best grip possible. Washer Head style provides the largest amount of surface area to seat firmly in the bottom of the pocket, especially for plywood or pine and ensures that the screw is not overdriven.

Material thickness: Use 25mm screws to join 13mm to 19mm thick timber, 32mm screws to join 19mm, 38mm screws to join 22mm to 32mm, 50mm for 32mm to 35mm timber and 62mm long screws to join 38mm thick workpieces. Suitable for use with pocket hole jigs including Kreg®.

N.B. Please remember to always use a drill driver with fitted with a clutch, using the lowest clutch setting required to do the job

Great screws, great service.

Used the 50mm screws to build a rough and ready workbench and it is pretty heavy duty when assembled. Screws seem to be holding really well.

I used the 25mm to make panels out of pine from pallets for the walls of my workshop. They hold well initially, but the thin diameter and the quality of the wood mean that they can't take too much of a beating.

Ran out half way through and ordered some new ones. They arrived next day even though I didn't order next day delivery so great service.

Shame the UJK pocket hole drill bit is prone to snapping.

You want to know what they forgot to say

You will want to know:
Do these have a cutting edge start? YES
Are these better than Trend? YES
Are the Torx heads better than square? YES
Is the metal of these screws very hard? YES
Which should I buy, 30mm x 3.5 or 30mm x 3.8?
I got 100 of each. I found that fixing to edge of mdf tiny cracks would appear 1mm earlier using 3.8, otherwise not a big difference. 3.5 seem adequate strength, both screw well into oak. 3.8 give a marginally stronger fix to oak but not a lot between them using a simple claw hammer extraction test. There is a slightly stronger fix to the screw head on the 3.8 but both are stronger than the fix to the wood, certainly for the 30mm length screws which will not be penetrating further than I would guess 15mm max. I recommend these screws. Make sure you also get a 150mm long torx driver, comes as a twinpack. UJK also do 4.0 gauge but I haven't tried those yet.
