Hints and Definitions
- THE MOST COMMON PROBLEM IS IMPROPER POCKET
DEPTH. i.e., joint is too tight
or too loose. see italics below.
- 6000 Series clips mate only with 6000 series shoulder screws and
- Any non-6000 series clip ( except 2032 series) will mate with any
non-6000 series shoulder screw (except the 1020B)
- For all # 12 SMT screws in wood, a 5\32" predrilled hole is
- For all # 14 SMT screws in wood, a 3/16" predrilled hole is
required. For 2000 series female shoulder screws,
a 5mm. predrilled hole is required.
- For 5000 series female shoulder screws, a
1\4" predrilled hole is required.
For 6000 series female shoulder screws, a
19/64" predrilled hole is required.
- For # 10 SMT mounting screws ( and with our
drill fixtures ), a 9/64 predrilled hole is required.
- An Apex X492 ( or equivalent ) bit is
recommended for driving male shoulder screws.
- When driving clip mounting screws into
predrilled holes in pocket, firmly clamp panel over pocket to prevent
cracking from mounting hole to mounting hole (especially with 32mm clips)!!
- When routing pockets, don't let sawdust build
up on back plate. An air jet can eliminate all dust
buildup. Also use our pocket depth gage regularly.
- Modular Systems has 1\2" shank router
bits available to meet pocket dimensions required by any Mod-eez®
- Use 511, 512 or 513 to mount 5055A or 5055B
- When pre-drilling thin gauge metal for
our thread cutting shoulder screws, use a # 21 bit for the 5043 and a
# 3 bit for the 6043
BLIP - the narrow point on a semi-locking
CLIP - The spring steel "female"
portion of the Mod-eez® fastener system
CLIP JOINT - Modular Systems, Inc.
PASS-THRU CLIP - A clip with both ends of the
ramp open, enabling a shoulder screw to enter, tighten, and then
"pop" through the clip.
R.T.A. - Ready to assemble. Furniture which is
not yet assembled, but is ready to be.
LOCKING CLIP - A clip with a locking tab which
flexes over the top of the shoulder screw head when assembled and
snaps down behind the head when assembly is complete.
NON-LOCKING CLIP - A clip with no locking or semi locking
features. It uses only friction to hold the joint together.
SEMI-LOCKING CLIP - A clip with a blip in the
raceway. Once assembled, disassembly requires passing the
shoulder screw the through the blip, flexing the ramp sides outward as
the shoulder screw passes, requiring more force than a non locking
clip, thus, semi locking.
POCKET - The machined ( routed ) recess in
which the clip is mounted and which ultimately hides the joint.
SEX BOLTS - "Female" shoulder screws
( i.e. threaded internally to accept the threaded portion of a
"male" shoulder screw ).
SHOULDER SCREWS - The "male" portion
of the Mod-eez® fastener system.
SURFACE MOUNT - Mounting the shoulder screw in
the pocket and the clip on the adjoining surface.
WINDOW - An opening in the side of a pocket to
provide an entry point for a shoulder screw or a screw driver.
For flush fit of panel "A" to panel "B" with shoulder
screw fully engaged in clip, locate shoulder screw from edge of "B" a
distance equal to location of rear clip mounting screw from edge of
"A" less dimension X ( X varies with the clip type, see
specifications for your clip ).
For instance, with the 32mm system boring, drill shoulder screw holes
.428" ( 11mm) closer to the edge than the rear clip mounting hole.
