310Slim®

FEATUREBEST SCREW FOR
THIN PLATE FASTENING

2 RECESS TYPES“6-LOBE ” AND “QUA ”

Flat head screw is not applicable on thin plate since you will not have enough space forcountersinking. 310Slim® achive nearly ﬂat surface without the head sticking out like truss
or pan head screws.

■ “6-Lobe” (hexalobular) is a standard recess as it iswell known in JIS or ISO (JIS B 1015/ ISO 10664).
Therefore, tools are easily can be purchased anywhereat your local DIY stores, hardwear supplier, andneedless to say, at SAIMA online shop.

××

Thin Plate■ “Qua” is the advanced cross recess which works
perfectly if special “Qua” bit applied. You can also use
standard cross recess driver for your convenience.

Flat Head

Truss HeadUnable toCountersink

Nearly Flat

Head Sticking out310Slim® will help to optimize a compact design.
Underhead “R” & “Un-threaded” part is designed very small to have bearing surface wide.

Prevent tools CAM-OUT
by using “QUA” bit.

GOOD TORQUE
TRANSMISSION■ Small “R” = Small clearance hole = Wide bearing surface ⇒ Stable Fastening■ Small “un-threaded” part = Fully threaded under the head ⇒ Best for thin plate fastening

310Slim®

“R” Underhead
Incomplete thread

Wide310Slim® has “6-lobe” or “Qua” recess to makethe head part extreamely thin. Both recesses
have good torque transmission rather than theothers such as cross recess or hex socket andthe bit ﬁts into the recess perfectly even therecess designed shallow. As a result, you canreplace from standard machine screw to310Slim® today.

Cross recess & Hex bit tend to easily slip out whenfasten if the recess is shallow. Thus, the head part will
be tall to get over this weak point.
