Page 6 of European Technica Assessment If in a European Technica Assessment according to ETAG 015 screws according to EN 14592 are specified to connect three-dimensiona naiing pates, Würth screws according to ETA-11/0190 may be considered equivaent, provided that the assumptions regarding the screws in the ETA according to ETAG 015 are met. Würth "ASSY pus VG" and "ASSY" screws with fu thread may be used for reinforcing of timber structures perpendicuar to the grain. Würth "ASSY pus VG" screws and fuy threaded "ASSY" screws with an outer thread diameter of d = 8 mm may aso be used for shear reinforcement. Würth screws with an outer thread diameter of at east 6 mm may be used for the fixing of therma insuation materia on top of rafters or on wood-based members in vertica façades. A.1.3 Use Conditions (environmenta conditions) The corrosion protection of the Würth screws is specified in Annex A.2.6. With regards to the use and the environmenta conditions, the nationa provisions of the pace of instaation appy. A.1.4 Instaation provisions EN 1995-1-1 12 in conjunction with the respective nationa annex appies for the instaation. A minimum of two screws sha be used for connections in oad-bearing timber structures. When fixing boards, battens or intermediate connections of wind braces ony one screw may be used. This aso appies for the fixing of rafters, purins or simiar on main beams or top pates, if the member is fixed with at east two screws in tota. Ony one screw may be used in structura connections when the minimum penetration ength of the screw is 20 d and the screw is systematic axiay oaded. In the case the screw is used to connect wood-based members the oadbearing capacity of the screw sha be reduced by 50 %. If the screw is used as tensie or compressive reinforcement of timber structures perpendicuar to the grain no reduction of the oad-bearing capacity of the screw is necessary. The screws are either driven into the wood-based member made of softwood without pre-driing or in pre-dried hoes with a diameter according to Tabe A.1.1. The screws are driven into wood-based members made of beech, ash or oak except LVL made from beech according to EN 14374 or FST according to ETA-14/0354 in pre-dried hoes with a diameter according to Tabe A.1.1.

Screws made from stainess stee may be driven into members made from softwood with or without pre-driing. Tabe A.1.2 Maximum penetration ength of the threaded part of Würth "ASSY" and "Jamo" screws made from carbon stee when driven into Beech LVL according to EN 14374 or in FST according to ETA-14/0354 without pre-driing Outer thread diameter [mm] Maximum penetration ength of the threaded part of the screws [mm] "ASSY" and "Jamo" screws with dri tip "ASSY", "Jamo" or "Amo" screws without dri tip 5.0-50 6.0 30 60 7.0-70 7.5-75 8.0 48 80 10.0 80 100 12.0 96 - The screw hoes in stee members sha be pre-dried with an adequate diameter greater than the outer thread diameter. Würth screws with an outer thread diameter of d = 14 mm and a ength greater or equa than 800 mm sha be ony driven in softwood in a guiding hoe with a diameter of 8 mm and a minimum ength of 10 percent of the screw ength.

In the case of fastening battens on therma insuation materia on top of rafters the screws sha be driven in the rafter through the battens and the therma insuation materia without pre-driing in one sequence. Screws may be used with appropriate washers according to Annex 9. After inserting the screw the washers sha touch the surface of the wood-based member competey. By fastening screws in wood-based members the head of the screws sha be fush with the surface of the woodbased member. For pan head, top head, back pane head, Emo-head, arge washer head, joist hanger screw head, kombi hexagona head, truss head, hexagona head and hexaobuar head the head part remains unconsidered.

Page 30 of European Technica Assessment ANNEX 7 Fastening of therma insuation materia on top of rafters A.7.1 Genera Würth screws with an outer thread diameter of at east 6 mm may be used for the fixing of therma insuation materia on top of rafters or on wood-based members in vertica façades. In the foowing, the meaning of the word rafter incudes wood-based members with incinations between 0 and 90. The thickness of the therma insuation materia may be up to 400 mm. The therma insuation materia sha be appicabe as insuation on top of rafters or for façades according to nationa provisions that appy at the instaation site. The battens have to be from soid timber according to EN 338/EN 14081-1. The minimum thickness t and the minimum width b of the battens are given in Tabe A.7.1: Tabe A.7.1 Minimum thickness and minimum width of the battens Outer thread diameter [mm] Minimum thickness t [mm] Minimum width b [mm] 6, 6.5, 7 and 8 30 50 10 40 60 12 80 100 14 100 100 The minimum width of the rafters sha be 60 mm. The spacing between screws sha be not more than 1.75 m. Friction forces sha not be considered for the design of the characteristic axia oad of the screws. The anchorage of wind suction forces as we as the bending stresses of the battens sha be considered for design. Screws perpendicuar to the grain of the rafter (ange = 90 ) may be arranged where required considering the design of the battens. A.7.2 Parae incined screws and therma insuation materia in compression A.7.2.1 Mechanica mode The system of rafter, therma insuation materia on top of rafter and counter battens parae to the rafter may be considered as a beam on eastic foundation. The counter batten represents the beam, and the therma insuation materia on top of the rafter the eastic foundation. The minimum compressive stress of the therma insuation materia at 10 % deformation, measured according to EN 826 1, sha be (10 %) = 0.05 N/mm². The counter batten is oaded perpendicuar to the axis by point oads F b transferred by reguary spaced battens. Further point oads F s are caused by the shear oad of the roof due to dead and snow oad, which are transferred from the screw heads into the counter battens. Instead of battens the foowing wood-based panes may be used to cover the therma insuation materia if they are suitabe for that use: Pywood according to EN 636 and EN 13986, Oriented Strand Board, OSB according to EN 300 and EN 13986, Particeboard according to EN 312 and EN 13986 Fibreboards according to EN 622-2, EN 622-3 and EN 13986. Ony screws with countersunk head, 75 head, FBS head or woodwork head sha be used for fixing wood-based panes on rafters with therma insuation materia as interayer. The minimum thickness of the wood-based panes sha be 22 mm. The word batten incudes the meaning of the above mentioned wood-based panes in the foowing. 1 EN 826:2013 Therma insuating products for buiding appications - Determination of compression behaviour Würth sef-tapping screws Fastening of therma therma insuation materia materia on top on of top rafters of rafters Fastening of the therma insuation materia on top of rafters Annex 43 7 Z33311.18 8.06.03-125/17

For further cacuations, the effective width w ef of the therma insuation materia may be determined according to: wef w thi / 2 (7.3) where w = minimum from width of the batten or rafter, respectivey t HI = thickness of the therma insuation materia E K HI (7.4) thi The foowing condition sha be satisfied: m,d fm,d M d 1 W fm, d For the cacuation of the section moduus W the net cross section sha be considered.

Page 35 of European Technica Assessment A.7.3 A.7.3.1 Aternativey incined screws and therma insuation materia non in compression Mechanica mode Depending on the screw spacing and the arrangement of tensie and compressive screws with different incinations the battens are oaded by significant bending moments. The bending moments are derived based on the foowing assumptions: The tensie and compressive oads in the screws are determined based on equiibrium conditions from the actions parae and perpendicuar to the roof pane. These actions are constant ine oads q and q. The screws act as hinged coumns supported 10 mm within the batten or rafter, respectivey. The effective coumn ength consequenty equas the ength of the screw between batten and rafter pus 20 mm. The batten is considered as a continuous beam with a constant span = A + B. The compressive screws constitute the supports of the continuous beam whie the tensie screws transfer concentrated oads perpendicuar to the batten axis. The screws are predominanty oaded in withdrawa or compression, respectivey.
