Size 3.5mmx16mm 200 per box . DISTINCT RIBS & TUCKS self countersinking into all timber and board materials No need to counterbore. 2. RE-INFORCED COLLAR prevents snapping AND gives depth for a wide, deep pozi bit to be inserted, therefore reducing the rish of "cam-out" 3. LUBRICATED, SHARP, WIDE, DEEP THREAD up to 40% reduction in driving resistance therefore less torque required. Quick and easy
