Mounting Screws Mounting/backing screws for lug casings and other shell-mounted hardware.Jump to section:CamcoGretschKentLeedyLudwigPearlRogersSlingerlandStarWFLYamaha Camco Camco lug mounting screws, Oaklawn era. 10-24 threads. Gretsch Three different styles of Gretsch Broadkaster Rocket lug mounting screws and washers. 10-24 threads. Gretsch round badge lug backing screws, introduced when their lug style changed in the early 1950s. 8-32 threads. Generally matte zinc finish, with separate nickel round washers. A variety of lengths of the same style screw were used for various hardware and shell thicknesses. This can make finding the correct length difficult for restoration work. Gretsch used 6-28 screws and speed nuts for Renown strainer and butt plates as well as tom and snare mufflers. Metal shelled snares used shorter screws in the same style. Beginning in the 50s for the Pratt bass drum muffler, Gretsch used 8-28 Phillips head countersink screws (and corresponding larger speed nuts). Early examples used hex nuts. This was a very early example of a US drum maker using a Phillips head fastener. Gretsch began using these hex head bolts with captive star washers in the late 1960s. They are the same thread as the earlier slot head round badge screws, and some sets had a mix of both types. There were two different lengths that corresponded to their two shell thicknesses. 8-32 threads. They began using self-tapping versions sometime in the 70s, which have led to a fair amount of stripped lug thread housings. Modern Gretsch mounting screws look much the same as those used in the 70s. These screws are from a 2000s strainer. Kent Kent lug mounting screws from their US-made drums. Late 1940s through perhaps early 60s. 10-24 threads. Leedy Leedy self-aligning lug mounting screws and backing plates. 6-32 threads. Leedy box lug mounting screws, 1920s-30s. 8-32 threads. Leedy Conn era lug mounting screws. 1930-mid-50s. These are later versions; earlier ones were nickel plated. 10-24 threads. Ludwig Ludwig & Ludwig lug mounting screws, 1920s-40s and possibly used even earlier. These are from wood shell drums; their metal snares used cup washers. 8-32 threads. Ludwig 3-ply lug mounting screws, 60s or early 70s. 8-32 threads. Ludwig 6-ply mounting screws, introduced in the 1970s as longer versions of the 3-ply screws. Both original and the later self-tapping versions are shown. Ludwig lug screws and cup washers from Supraphonic or Acrolite snare drums. Later versions had a slot cut into the hex head. Similar cup washers were also used on some mounts and brackets. These logo washers were used with 1610 and other bracket mounting hardware. 1960s-80s. Ludwig slotted head lug mounting screws, 8-32 threads. Pearl Pearl mounting screws, 4mm-.7 threads Rogers Rogers bread and butter lug backing screws, 1950s-early 60s. 10-24 threads. Note the two different sizes of captive round washer, though these screws all came from the same drum. The larger washers were for the rear ends of the lugs, where outward tension on the shell would be greater. As the bread and butter lug mounting screw housing was flush against the shell, some drums had these screws installed with small metal guard shims to protect the wood under high tension (as if the lugs themselves would withstand it). These star/tooth washers were used with 8-32 lug screws before Rogers began utilizing captive washers. 1960s-early 70s. Rogers Fullerton era lug mounting screws. 8-32 threads. Earlier versions were hex head without the slot. Slingerland Slingerland Radio King lug mounting screws, late 1930s- through sometime in the 40s. 8-32 threads, 3/8" and 5/8" lengths. The longer screws were needed for where the large reinforcement rings protruded under part of the lug. A later version of the Radio King mounting screws, with captive star washers. These were sometimes used alongside the earlier style on the same drum. Slingerland logo cup washers, from left to right: 20s eyelet guide platform; early 40s, later 40s, and early 50s lug mounting washers. Each subsequent version of these parts was lighter and thinner than its predecessor. The last aluminum versions had no stamped text. These Radio King floor tom bracket mounting washers have larger holes. A few different versions are shown. Slingerland 50s lug mounting screws, a style introduced with the Sound King lugs. 1/4" and 3/8" lengths, 8-32 threads. Slingerland late 50s through early to mid-60s lug mounting screws. Similar to the previous version but with an X rather than simple slot. 1/4" versions were nickel plated. Similar to the previous version but with an X rather than simple slot. 1/4" versions were nickel plated. The longer, 3/8" version of the same style from the same era was zinc plated. 8-32 threads. Slingerland Set-o-Matic bracket mounting washers, 1960s-70s Slingerland mid-60s-early 70s lug mounting screws. The slot/hex head became a simple hex head in the late 60s. 8-32 threads. Three lengths were used; 5/16, 3/8 and 7/16 inches (measured below the captive washer). Slingerland Sound King spur bracket mounting screws. 10-32 threads. Slingerland lug mounting screws 1970s-80s. Small hex head the same size as Ludwig's mounting screws, large washers. 8-32 threads. Sonor Sonor 60s teardrop lugs used posts attached to the main casting, and chrome terminal nuts inside the shell. 4mm-.7 threads. Different heights of posts and nuts were used for wood or metal shells of different thicknesses. Star/Hoshino Gakki/Tama Star typically did not use captive washers on their mounting screws. These screws are from 70s Star snare drum lugs. 4mm-.7 threads. WFL Several varieties of WFL lug mounting washers. 1930s-50s. Yamaha Yamaha lug mounting screws and separate washers, 1960s-70s. 4mm-0.7 threads.
