Types of NAAMS Spacers
2-Hole Spacers
NAAMS shims in the 200 series are 60mm by 50mm ±1.0 with two Ø 10.5mm holes +0.3 -0.0 tolerances set 30mm apart. The thickness is specified by the specific NAAMS code.
3-Hole Spacers
NAAMS spacers in the 300 series are 46mm by 25mm ±0.5 with three Ø 10.5mm holes +0.3 -0.0 tolerances set 15mm apart. These are offered with a slotted design and narrow design as well. The narrow digns have the same configurations as regular the regular ASP300 series but with a 20mm width. S-slotted series have a 20mm width ±1.0 with a 9.0mm by 20mm slot. The thickness is specified by the specific NAAMS code.
4-Hole Spacers
NAAMS spacers in the 400 series are 61mm by 25mm ±0.5 with four Ø 10.5mm holes +0.3 -0.0 tolerances set 15mm apart. These are offered in an S-slotted series as well with a 9mm by 30mm slot that comes with a 20mm ±1.0 width. The thickness is specified by the specific NAAMS code.
5-Hole Spacers
NAAMS spacers in the 500 series are 76mm by 25mm ±0.5 with five Ø 10.5mm holes +0.3 -0.0 tolerances set 15mm apart. The thickness is specified by the specific NAAMS code.
6-Hole Spacers
NAAMS spacers in the 600 series are 50 mm by 63mm ±1.0 with 6 Ø 10.5mm holes +0.3 -0.0 tolerances set 15mm with three holes 15mm apart and three holes parallel 45mm ±0.2 on the opposite side. These S series spacers are offered with a double slot design. Slots are 9mm by 20mm set 40mm apart and come with a 36mm width. The thickness is specified by the specific NAAMS code.
3-Slot Spacers
NAAMS 3-slot construction spacers are slotted spacers with dimensions of 110mm by 40mm. The three slots are 35mm apart Ø 10.50mm ±0.20. Thickness is specified by the specific corresponding NAAMS code.
Spacer for 60 x 60 and 70 x 70 Mounting
NAAMS spacers in the ACS600 series are construction spacers with an 8-hole design. Dimensions are 100mm by 100mm with hole configurations of four Ø 10.5mm ±0.20 and four Ø 19.0mm ±0.20. The thickness of spacers is specified by the corresponding NAAMS codes.
Spacer for Shock Bracket
NAAMS Spacers in the 700 series are meant for shock brackets. They come with a 5 hole design with dimensions of 76mm by 57mm. The hole configurations include a single 42mm drill through hole with 4 surrounding 9.0 mm thru holes. The thickness is specified by the corresponding NAAMS code.
All tolerances are set to ±0.5 for 0 places, ±0.3 for 1 places, and ±0.03 for 2 places.
