TUBE-LOK® FASTENERS

DRIVING THE FASTENER

The Simplex Tube-lok® nail is a two-part fastener.
To assure proper holding and sealing, it is essential that both parts of the nail be driven properly. First, drive the tube portion with the large head firmly into the roof deck being sure that:

1. The head is flat and parallel with the roofing material.
2. The head is firmly seated but does not cut the roofing material.

Push the insert nail into the tube. Now, to drive the insert is best accomplished with a light tap to start the insert, rather than a heavy blow. If the insert should bend before being completely seated in the base tube, remove the bent insert and drive another (extra inserts are included with each package to allow for this possibility), If the second insert also bends before completely entering the tube, remove the entire nail, tube and all, and repeat in a slightly different location as you are engaging a very hard object in the material.

NEVER LEAVE A BENT INSERT IN THE TUBE AND NEVER LEAVE A TUBE WITHOUT AN INSERT.

BUILT-UP ROOFING

In the application of built-up roofing systems on low-density fiber decks, use the 1" Tube-Lok® nails. The roofing manufacturers' nailing specifications should be followed at all times. We suggest 2 minimum pattern of a nail every two feet and additional nails where needed at edges and openings. Increase nails per square on roofs of 1" pitch or greater is suggested. Nailing pattern must be based on roofing manufacturers' specifications, material to be nailed, condition of deck and contractors experience.

ASPHALT SHINGLES

In the application of asphalt shingles to low density fiber decks, use the 1 3/4 " galvanized Tube-Lok® nail.

A.     All shingles must be of the seal-tab or self-sealing variety.

B.     Three or four Tube-Lok® nails are required per shingle. However, in this regard, follow the nailing specifications of the roofing manufacturer at all times with regard to number of nails per shingle and location, keeping in mind the diameter of the head used in the manufacturers' specification is smaller than 1", move to a higher location.

C.     If the Tube-Lok® nail is applied below the seal-tab line, the head of the nail must be sealed with a suitable plastic such as plastic asphalt cement or heavy grade flashing cement as manufactured under Specifcation No, SS-C- 153 Type 1. We further recommend that this material be applied by trowel rather than by applicator tube and nozzle. The nail head should be thoroughly covered to assure sealing.

D.     If the nail is applied above the seal-tab line, it must be at least 1 1/2" above the cut or above the seal-tab line, whichever is the higher.

E.      Never place the Tube-Lok® nail directly over the seal-tab line.

F.      For roofs of less than 4" in 12" pitch, seal each nail head as outlined in (3) above, regardless of the nail location with reference to the seal-tab line.

This application has been used with success using the 1 3/4" galvanized Tube-Lok® nails, Slate, shingles over low-density fiber decks should not be applied on slopes less than 4 1/2" in 12". Care should be taken when driving the Tube-Lok® nail to prevent cracking of the shingles. On slate applications, each nail head should be coated with a mastic or sealant that will not run and discolor or otherwise detract from the appearance of the roof. In some applications, it has been specified that each nail be driven through a small piece of roofing felt which acts as a gasket or buffer between the nail and the shingles. It is also suggested that this method helps prevent possible cracking of the shingles.

WOLVERINE PORCELAIN ENAMEL STEEL SHINGLES

The 1 3/4" Galvanized Tube-Lok® is specified by the shingle manufacturer on the application of steel and enamel shingles to all low-density fiber decks. Holes are pre-punched in the shingles to take the Tube-Lok® nails. In all instances, the shingle manufacturers’ specifications for nailing are to be followed. This includes slope of roof acceptable, number of nails required, etc. Application information on this shingle can be obtained by contacting the manufacturer.

LUDOWICI ROOFING TILE

There have been a limited number of specifications for this application. The 1 3/4" Tube-Lok® is specified and the tile manufacturer specified the nailing and the acceptable deck. In most instances, this application is approved at an architect's request. All experience has been on slopes of 4" in 12" or greater. In these applications, a great deal depends on the weight of the tile and the sheer load created by the slope of the deck. The 1 3/4" Tube-Lok® nails have been found to give sufficient rigidity to properly hold the shingles. It is recommended that the tile manufacturers be consulted on nailing specifications.

In the application of asphalt shingles to low-density fiber decks, use the 1 3/4" Tube-Lok® nail.

1. All shingles must be of the self-sealing type. Compensation for large head is necessary in placement of the nail in shingle.

2. Three or four Tube-Lok® nails are required per shingle. Follow the nailing specifications of the roofing manufacturer at all times with regard to the number of nails per shingle and the location.

3. If the Tube-Lok® nail is applied below the seal-tab line, the head of the nails must be sealed with a suitable plastic such as plastic asphalt cement or heavy grade flashing cement as manufactured under specification # SS-S-153 Type l. It is recommended that this material be applied by trowel rather than by applicator tube and nozzle to ensure that the nail head is thoroughly covered to assure sealing.

4. 4. If the nail is applied above the seal-tab line, it must be at least 1 1/2" above the cut or 2" above the seal-tab line, whichever is higher.

5. Never place the Tube-Lok® nail directly over the seal-tab line.
