 These kits were designed specifically for the Van's RV series aircraft and we have put together various kit configurations to suit anyone's preference.

MilSpec's cowling fastener kits have been developed and refined with exhaustive research and over 14 years of real world field experience. These stainless cowling kits use MilSpec's FAA approved 4000 series fastening system with our MS245 adjustable depth receptacles. Kits are available with either a collared, slotted head or cross recess (Phillips) head studs. These kits are for the main engine cowling. Optional fasteners are available for other panels such as the oil door, interior panels etc. These options are listed at the bottom of this page.

  • Are These the Same as Other Brands of Fasteners ?
  • No they are not, We are the Original Manufacturer of These Components and Have Been Continuously Improving Them Since 1994. We Invite and Welcome Comparisons with our Competitors. Because the More You Know About Fastening Systems, the Better We Look.
     CLICK HERE TO SEE WHY !

  • What Do You Get With a MilSpec Kit ?
  • Genuine MilSpec, FAA Approved, Heavy Duty Fasteners conforming to TSO-C-148 and Mil-F-5591
  • Stainless Stud Assemblies 4002-2S (collared slotted) or 40S5-2S (Phillips/cross recess).
  • Stainless MilSpec Standard Grommets MS-OS
  • Stainless Grommet Retainers R4GS
  • Standard Aluminum Adjustable Depth Receptacles MS245
  • Drill Templates Included for Accurate Hole Size, Spacing and to Prevent "Walking" of the UniBit
  • MilSpec Kits Include More Fasteners Than Competitive Kits (3.5" spacing Vs 4")
  • Complete Kits Include Nose Section Hardware (screws, washers, nut plates)
  • Detailed Instructions with Tips From Our 14 Years of Hands on Installation Experience.
  • 10% Discount on Installation Tools When Purchased With Any Kit.
     
  • What are the Installation Parameters ?
  • Each Builder Will Have Their Own Preference but, These Kits Assume Approx. 3.5" Spacing Between Fasteners. Much wider spacing can be used with our MS2D woven fiberglass tape
    Reinforcement strips.
  • Distance From the Edge of the Cowling to the Center of the Fastener Hole Requires 5/8" Min.
  • The Support Lip Width Should be a Minimum of 1-1/8" (preferably 1-1/2").
  • The Minimum Thickness for the Support Lip is .040"
  • Bulging Between Fastener Holes is not a Concern With These Kits When Used on Newer Generation Cowlings but, for Earlier Cowls Try our MilSpec MS2D Reinforcement Material. This is a simple strip of woven fiberglass tape that can be laid up adjacent to the fastener line to stiffen the cowling along its edge.
