Hi All
Just received some 10 x 100mm Turbo Coach Screws from Screwfix. The catalogue description reads: "Make any job faster with Zinc-plated, Yellow-passivated Coach Screws, combining the unique design of the Turbo Screw along with a self-cutting point. (May require pilot holes in harder substrates.) Unique Rifled Shank for Easier Driving & Reduced Splitting, Self-Drilling Point". You simply cannot drive these into softwood without a large pilot hole!!!! Let alone 'harder substrates'. I tried with my 14.4v driver (loads of torque), a 350w mains driver and a 500w variable speed drill. No chance at all, they go in for about an inch and thats it. Screwfix have responded to the problem by offering a credit without collection to be fair to them, but I'm still going to lose time on a large decking job. I've ordered some 6.3 x 100 Exterior Timber Screws at double the cost in the hope they will drive OK. Never trust a catalogue description! -- Dave The Medway Handyman www.medwayhandyman.co.uk 01634 717930 07850 597257 |

When you consider that they are 10mm in diameter then it is hardly reasonable in my reckoning asking an electric screwdriver to put them in - I would actually say that I think Screwfix are being quite reasonable in offering a credit as I think you have translated the advert as you wanted to. I'm screwing edge on into 100 x 50 softwood and again with that diameter of screw I reckoned that a 5mm pilot hole and lubrication with beeswax was good practice anyway and I've had no difficulties.

You really expected a 10mm coach screw to self-tap?
I pilot drill anything over 5mm (less in hardwood), and I'm using a cordless impact driver to drive them home. |

I've used these (150mm x 10mm ones) and my elu 12v impact driver put
them into softwood fine without a pilot hole. That's good going, even for an impact driver. You're pushing the whole150mm into the timber? I use 6x100m and similar turbogold a lot, mostly in mahogany or oak, predrill at 3-4mm (with a clearance hole in the attached timber) and my 14.4v bosch impact driver can start to slow. Pushing harder than that and it's very possible to snap a screw. Lube helps a bit. 10mm is unlikely to snap, but what about it simply locking solid (and unwilling to reverse out) before fully inserted? How close to an edge can you go with 10mm, without pre-drilling? Did you lube them? Did you get any cracking along the grain? |

I use 6x100m and similar turbogold a lot,
Thats quite a screw. Have a look at how modern timber windows are made. They often scarfe the profiles to each other and use very large screws to secure them - no fancy wood joints. One advantage is that all the parts can be fully treated on all sides before assembly - so the end grain is protected if moisture eventually creeps in. |

From the Trada website:
The majority of Scandinavian window manufacturers no longer use tenon joints for the sub-frames. The jambs and mullions are end cut to match the sill profile, but the connection often consists of a glued joint and long screws driven through the sill from the underside into the ends of the vertical members. This simplifies manufacture and reduces the length of timber necessary for the vertical members because of the omission of the projecting tenon. These screwed connections are sufficiently strong for handling, and once the sub-frame is installed and fixed, there is little strain on the joints. http://www.trada.co.uk/techinfo/asse...sign%2Cdesigns |

I've just built a pergola using M8x150 Turbo Coach Screws from Screwfix. They went straight in to treated softwood using a variable speed mains drill. I did final tightening (1/2 turn or so) by hand using a socket & ratchet. No problem there. My cheap 16V battery drill wouldn't look at them but I didn't expect it to. The mains drill did get hot so I had to cool it by either running off load for a minute every couple of screws or arranging my work to give it time between uses. A two speed gearbox driven drill would probably have coped better. John |

Where on earth do you get your luck from Dave? On 8x1.5's from the screwfix ranges that claim no pilot hole all I seem to get is split f**king wood - so much so that I've given up and gone back to Pilot Holes and Quicksilvers....seems that lady luck ain't on my side much ;-) Cheers Dan. |

My 500w Skill wouldn't have it. What size drill? An old B&D 500W. D143V, 3000 RPM. I was driving M8 remember so the torque required for M10 is 25% more. Add to that the extra friction due to extra surface area and you may need up to 40% more torque. A gearbox drill should give that though. John |

I've put 4" x 10 straight into softwood with no problem and no splitting at all. 1.5" x 8 go into anything with no splitting. Are they the same as the Screwfix ones? -- Dave The Medway Handyman www.medwayhandyman.co.uk 01634 717930 07850 597257 |

Like you I haven't found pilot holes necessary, I'm using a Metabo 12v cordless to drive them which I chose specifically because it can deliver up to 50Nm of torque. -- Chris Green |

Hi, Better to drill a pilot hole as any splitting can let in water and the decking rots from inside. However few people know this, so you're OK using anything. cheers, Pete. |

Hi, Better to drill a pilot hole as any splitting can let in water and the decking rots from inside. However few people know this, so you're OK using anything. cheers, Pete. Try soaping the threads first. This usually reduces friction enough for them to drive straight in.. And use some welly on the screwdriver. I've found nearly any screw can be whacked through almost anything given enough torque. The limiting factor is the screw shears or the cross head rips out. Or both.. If all else fails hammer them in and use a screwdriver on the last few turns. Even on hardened oak its normally possible to not use a pilot hole. |
