2.0 USES
The Hillman
TM
Structural Screws are used for wood-to-wood
connections that are designed in accordance with the IBC.
For structures regulated under the IRC, the screws may be
used where an engineered design is submitted in
accordance with IRC Section R301.1.3.
3.0 DESCRIPTION
3.1 Hillman
TM
Structural Screws:
The Hillman
TM
Structural Screws are partially-threaded
dowel-type fasteners designed to be installed in wood
without drilling a lead hole. The screws have a reamer knurl
between the smooth shank of the screw and the screw
threads and have a Type 17 point.
The Hillman
TM
Large Hex Washer Head Screws have a
hex head with a large integral washer. The screws are
formed from carbon steel and are case hardened. They
have a hot-dip galvanized coating complying with ASTM
A153 Class C.
The Hillman
TM
Wafer Head Screws have a flat,
countersunk head with ribs. The screws are formed from
Type 316 stainless steel.
See Table 2 for screw dimensions and Figure 1 for
depictions of the screws. Product (brand) names for the
report holder and the additional listee are presented in Table
1 of this report.
3.2 Wood Members:
For purposes of connection design, sawn lumber members
must have an assigned specific gravity as indicated in the
tables in this report. Assigned specific gravity (ASG) for
sawn lumber must be determined in accordance with Table
12.3.3A of the ANSI/AWC National Design Specification for
Wood Construction
®
(NDS) (Table 11.3.3A of the NDS for
the 2012 IBC). Unless otherwise noted, sawn lumber
members must have a moisture content of 19 percent or
less.
For the purposes of connection design, structural glued
laminated timber (GL) must have a Specific Gravity for
Fastener Design (addressed in Tables 5A through 5D of the
NDS Supplement), as indicated in the tables in this report.
Unless otherwise noted, GL must have a moisture content
of less than 16 percent.
When designing connections with screws installed into the
face of cross-laminated timber (CLT) panels fabricated with
sawn lumber laminations, all of the laminations must have a
minimum assigned specific gravity in accordance with the
NDS as indicated in the tables in this report. Moisture
content must be less than 16 percent.
Use of the screws in engineered wood products (EWP)
other than those addressed above is outside the scope of
this report.
For wood-to-wood connections, the tabulated side
member thickness is an absolute value (not a minimum or
