Questions & Answers
Need black screw to install 6 x 6 black post cap on my deck. Cap has hole in top. Do I also need a washer for it.
Please check with post cap manufacturer for installation instructions and minimum requirements of fastener needed.
I see reading through questions that these are not recommended for red cedar because of tannins and staining, is this the case for redwood as well?
Thank you for the honest answer.
We would not recommend this fastener for Redwood as it is also potentially high in tanins (acids) similar to cedar. Although the risk of staining due to a reaction with the steel in the fastener is low, the only way to be 100% sure that no reaction occurs is to use a stainless steel fastener.
Screw goes through the first 4x4 but stops shortly after reaching the second,why?JG
Please call Fasten Master @ 800-518-3569 and ask for Fasten Master technical department so we can better assist you.
Can 8” screw be installed between studs through wall bottom plate and composite sub floor decking into rim joist on an off grade storage shed. Would it help prevent uplift of building from raised wood foundation ?
Can washers be used to increase screw head contact area ?
Can these be used to combine 3 2x12s to make a beam for a clear roof?
Yes, these 4" TimberLOKs can be used but best if staggered from both sides of the beam as they are 1/4"-1/2" shy of the full 4-1/2" depth. A 4-1/2" HeadLOK can be used from one side as they match the depth. Typically, a row of 3 fasteners every 16" is sufficient for typical roof loads (no snow or loads from additional dead weight). If you have further questuions feel free to call us at 800-518-3569.
can these be used to hang a swivel hammock swing
Not knowing all the variables, screw has a shear capacity of 200 lbs. not knowing all the variables, its hard to give a better answer. How are you hanging the hammock, bracket? what are you screwing into?
Are timberlok fasteners rated to be submerged in water/used to anchor pressure treated timbers together for a fresh water lake waterfront lake wall where the first 4 rows are under water.
The TimberLOK Fasteners are rated for use in woods treated for above ground and ground contact in general use conditions - defined by the AWPA as UC4A treatment. The application you describe would require treatment levels for ground contact in heavy duty (UC4B). For this condition a stainless steel fastener would be recommended for matching performance.

3/8 in. x 10 in. Star Drive Low Profile Washer Head RSS Alternative Lag Screw
GRK RSS Rugged Structural Screw has a patented design and made of specially hardened steel to provide customers with high tensile, torque and shear strength. The sharp threads and points bite instantly into material, including hardwood, reducing the splitting effect due to smaller shanks. The GRK RSS series screws that are 3-1/8 in. and longer have 6 CEE threads which enlarge the screw hole for the non-threaded portion of the fastener, allowing the wood to settle easily and increases the screw's drawing strength.
