The Falcon 002770-016-30 is the OEM T/RU Series Insert Screw, 10-32 x 1 inch, documented in the Falcon T Series Service Manual (doc 108002). It is the through-bolt fastener used to secure the outer trim and inner spindle assembly over the lock chassis in all Falcon T Series and RU Series cylindrical locks. Two screws are required per lock. Available (3-4 weeks).

The thread specification is 10-32 UNF (Unified National Fine) at 1 inch length. The screw ships with thread sealant applied to the threads, confirmed in the official Falcon T Series product documentation: "trim is through-bolted with two 10-32 screws coated with thread sealant." The sealant prevents the screw from vibrating loose in high-traffic, high-cycle installations where mechanical fatigue is the primary cause of hardware failure.

What the 002770-016-30 Insert Screw Does in Falcon T Series and RU Series Locks

The Falcon T Series cylindrical lock uses a specific installation sequence. The lock chassis mounts first, secured to the door by threaded mounting nuts. Once the chassis is in place, the completely preassembled outer trim and inner spindle assembly are positioned over the chassis from the door faces. The two 002770-016-30 through-bolt screws pass through the outer trim and inner spindle assembly and draw the complete trim assembly tight against the door faces, holding both sides of the lock in correct alignment with the chassis.

Without the correct insert screw, the trim assembly cannot be properly secured to the chassis. A stripped, corroded, or missing 10-32 screw results in trim movement, lever sag, and eventual disengagement of the spindle from the chassis, which causes the lever to spin without operating the latch. In high-traffic institutional installations, the 002770-016-30 is the fastener that maintains the mechanical integrity of the entire lock assembly throughout its service life.

Falcon T Series Cylindrical Lock: Function Coverage for the 002770-016-30

The 002770-016-30 applies to all keyed and electrified T Series functions documented in the Falcon T Series Service Manual. The T Series is certified to ANSI/BHMA A156.2, Series 4000, Grade 1 and is UL Listed for 3-hour fire doors. Functions covered include:

T101 (Passage), T291 (Hospital Privacy), T301 (Privacy), T351 (Closet), T381 (Classroom Security), T411 (Asylum), T501 (Entry), T511 (Entry/Office), T521 (Office), T561 (Classroom), T571 (Dormitory), T581 (Storeroom), T851 (Storeroom, Electrified Fail Safe), and T881 (Storeroom, Electrified Fail Secure).

The T Series accepts any manufacturer's interchangeable cylinder, including Falcon, Arrow, Best, Corbin Russwin, Medeco, Sargent, Schlage, and Yale formats. The cylinder can be removed for rekeying without disassembling the lock from the door. The 002770-016-30 insert screw remains in place during cylinder service and does not need to be disturbed for standard rekeying operations.

Falcon RU Series Cylindrical Lock: Insert Screw Coverage

The Falcon RU Series is the retrofit cylindrical lever designed for installation over existing door preparations without requiring door modification. Like the T Series, it uses the 10-32 through-bolt installation method. Per the official RU Series product documentation: the lock "installs with 10-32 through-bolt screws with thread sealant for extra security and resistance to vibrating loose."

The RU Series functions covered include RU381 (Apartment Exit), RU411 (Asylum), RU501 (Entry), RU511 (Entry/Office), RU521 (Office), RU561 (Classroom), RU571 (Dormitory/Corridor), RU581 (Storeroom), RU851 (Electrified Fail Safe), and RU881 (Electrified Fail Secure). All keyed RU Series functions include a clutching feature on the outside lever. The 002770-016-30 is the same fastener used across both product lines.
